Can You Train With a Pacemaker or Defibrillator? The Device-Door Audit: The Door Where the Heart Rate Is a Setting, Not a Reading — Where the Gym's Two Default Scripts, the Push-Through One (It's Just a Battery, I Feel Fine, Train) and the Fear One (a Device Means Shocks and Broken Leads, the Gym Is Over), Both Fail the Reader (the Registry Column: Lampert's 372 Athletes Followed a Median 31 Months — Zero Deaths, Zero Resuscitated Arrests, Zero Shock-Related Injuries, While 10% Took Shocks in Practice Against 6% at Rest; the Rule Column: the Conservative 2006 Consensus → Task Force 9 2015 Retiring the Class-IA Ban → the 2020 ESC Sports File and the 2021 ESC Pacing Guideline Programming the Athlete's Device Instead of Grounding Him; the Arm Column: Deering's Two Weightlifting Lead Fractures Crushed Between Clavicle and First Rib — the Kernel Inside 'Don't Raise the Arm' — Against E-MOTION's 200 Patients Mobilized at 3 Hours With Lead Dislodgement 3% vs 4% at 24 Months; the Heart-Rate Column: the Paced Athlete Whose Ceiling Is a Programmed Number, Where Rate-Response Sensors and RPE Replace the Chest Strap; the Training Column: Fitchet's RCT — Cardiac Rehab Raised Exercise Time 16% and Cut HAD Anxiety From 13.4 to 8.1 With Zero Discharges During Exercise; the Pool Column: Salty Water Stymies the Shock — the Physics That Prices the Swimming Door; the Magnet Column: the Phone in the Pocket Over the Device; the Honesty Column: a Registry Is Not a Randomized Trial, and 10% Still Shocked) — the Answer Is Cleared, Not Grounded: Heal the Pocket First, Program the Rate Like the Variable It Is, Price the Pool, Keep the Magnets Off the Hardware, and Let the Device Clinic Read the Dated Ledger

A pacemaker or an implantable cardioverter-defibrillator (ICD) is the file where the internet's two default scripts — the push-through script: it's just a battery and a wire, I feel completely fine, the doctor is being conservative, keep the program running and the fear script: a device means shocks in the gym, broken leads under the bar, the gym chapter is over — both fail the reader at the exact door he walked in through, because this reader is one of two people: the fresh-implant reader, discharged with "don't lift the arm above the shoulder for a few weeks" and no numbers attached to any word in it, asking what the rule actually protects against, or the cleared-device reader, months out and asking the only question that matters to him: which parts of training are medicine here, which are noise, and which are the real hazards — the pool, the magnet on the wrist, the maximal grind, the chest-first tackle. The fear script dies on the registry column, because the largest file ever assembled on athletes with defibrillators — 372 of them, running, basketball and soccer, followed for a median 31 months — recorded zero deaths, zero resuscitated arrests and zero shock- or arrhythmia-related injuries during sports, while a randomized trial put ICD patients through a full cardiac-rehabilitation program with zero discharges during the exercise sessions and anxiety scores nearly halved [1][13]. The push-through script dies on the same file's fine print, because 10% of those athletes took shocks during competition or practice anyway [1], two weightlifters fractured pacemaker leads exactly where the folklore says the danger lives — crushed between clavicle and first rib [9] — and a Zurich correspondence asked, in its own title, whether salty water stymies the shock [14]: the pool is priced differently from the platform, and the phone resting in the pocket over the device is a magnet sitting on a therapy switch [15]. So the fences come first. First: the emergency fence — a shock you felt fine through is a same-week clinic call, but a shock with chest pain, fainting or breathlessness, or two shocks in a row without recovery between them, is emergency services now: the storm file outranks every set in every logbook [1][6]. Second: the healing fence — the first weeks after implant price the pocket and the leads' consolidation; the arm rule protects a real failure mode [9][10], the month-long sling outlived its evidence [10][11][12], and the graded reintroduction of the operated arm belongs to the implanting center's protocol, not to the locker room's [7]. Third: the disease fence — the device is the smoke alarm, not the fire: the condition that earned it (the post-infarct file, the cardiomyopathy, the channelopathy, the conduction disease) owns its own training rules, and the device door only prices what the hardware adds on top [5][6]. Fourth: the water fence — the swimmer who loses consciousness in the water drowns before the arrhythmia finishes, which makes swimming the door's highest-attention modality, priced with the device clinic rather than banned from it [6][14]. Fifth: the magnet fence — phones, smartwatches and accessories carry magnets strong enough to suspend therapy (magnet mode); they live centimeters away from the pocket, never on it [15]. With the fences standing, the file underneath is one of the most instructive in this library's cardiac wing: the door is real, but the modern era retired the blanket ban — Task Force 9 in 2015, the ESC sports file in 2020 and the ESC pacing guideline in 2021 program the athlete's device instead of grounding him [5][6][7].

The short answer: yes — cleared, not grounded

Strip the file to its spine. The registry column: 372 athletes with ICDs aged 10–60, median age 33, a third of them female, 60 of them competitive varsity-level — a median 31 months of organized sport produced no deaths, no resuscitated arrests and no shock- or arrhythmia-related injuries, with shocks in 10% during competition or practice, 8% during other physical activity and 6% at rest [1]. The recreational splice: the European cohort of the same registry found recreational athletes — older, more often male, more often implanted prophylactically — took fewer appropriate and inappropriate shocks during activity than the competitive arm, with no shock causing death or injury [2]. The young splice: 129 athletes with ICDs averaging 16 years old, 42 months of follow-up, 27% shocked, no serious adverse sequelae, lead malfunction no commoner than in unselected young ICD populations [3]. The rule column: the conservative 2006 consensus [8] gave way to the 2015 AHA/ACC task force judging it reasonable for athletes with ICDs to return to competitive sport when stable [5], and the ESC files now address the athlete with a device by programming — rate-response ceilings, detection intervals, follow-up cadence — rather than prohibition [6][7]. The arm column: the month-long sling protects against a real mechanism — leads crushed between clavicle and first rib in two weightlifters [9] — but 200 patients randomized to mobilization at 3 hours after implant showed lead dislodgement at 24 months of 3% versus 4% (p=0.99) [10], and the scoping review of the field reads the sling out of the evidence and the graded-return protocol into it [11][12]. The training column: the randomized crossover trial of comprehensive cardiac rehabilitation in ICD patients raised exercise time 16% (p=0.001), cut hospital-anxiety scores from 13.4 to 8.1 (p<0.001), and recorded zero ventricular arrhythmias or discharges during the exercise components [13]. That is the audit in one paragraph: the hardware is not the ban the folklore prices, the hazards it actually prices are the pocket's first weeks, the water, the magnet and the untreated underlying disease — and the gym, priced correctly, is where the device patient's physiology improves [1][6][13].

What the hardware actually is: a battery, wires, and a programmable opinion

The mechanics in a paragraph. A pacemaker treats slow rhythms — it senses the heart's own beats and paces when the native rate drops below a programmed floor, with sensors that raise the paced rate when the body starts moving. An ICD is a pacemaker plus a shock box: it watches every beat for dangerous fast rhythms and delivers pacing or a shock to break them. Both live as a metal can in a pocket under the collarbone (or, in some ICDs, under the arm without touching the heart at all), with leads — insulated wires — threaded through veins into the heart, or wrapped around it outside. The scale is industrial: the 11th world survey counted 1,002,664 pacemakers implanted or replaced across 61 countries in the calendar year 2009 alone — 737,840 of them new implants [18], a population that has only grown since, and Brazil's public system alone implanted 216,927 cardiac devices across a recent twelve-year window [21]. Three properties of the hardware matter to the training reader. First, the heart rate on the screen is a programmed setting, not just a reading: a paced athlete's ceiling may be a number a technician chose, and rate-response sensors estimate workload from motion or physiology rather than reading the heart's intent — the chest-strap number that once anchored every training decision has to be re-negotiated with the device clinic [7][16][17]. Second, the pocket and the leads have a healing calendar: the first weeks price lead consolidation and pocket stability, which is the true content of the arm rule [9][10]. Third, the device is therapy, not disease: it was implanted because of something — a conduction block, a scar, a channelopathy, a cardiomyopathy — and that something keeps its own training file, which is why the guideline question is never "device or no device" but "which underlying condition, which sport, which program" [5][6].

The registry column: 372 athletes, zero catastrophes, 10% shocked

Every door in this library eventually publishes the column that retires its folklore, and this door's is the ICD Sports Registry — the study the blanket ban never survived. Lampert and colleagues enrolled 372 athletes with ICDs, aged 10 to 60 (median 33; 89 of them under 20; 33% female), of whom 328 played organized sports and 44 raced in formats classed high-risk; 60 were competitive varsity or traveling-team athletes, running, basketball and soccer the most common sports; 42% carried a pre-ICD history of ventricular arrhythmia [1]. Over a median 31 months of follow-up with every shock and outcome adjudicated by two electrophysiologists: zero occurrences of either primary endpoint — death or resuscitated arrest, and arrhythmia- or shock-related injury — during sports [1]. The shocks were real but survivable: 49 shocks in 37 athletes (10% of the population) during competition or practice, 39 in 29 (8%) during other physical activity, and 33 in 24 (6%) at rest — exercise concentrated the risk without manufacturing catastrophe, and eight ventricular episodes produced multiple shocks each [1]. The splices sharpen both edges. The European cohort compared recreational against competitive athletes: the recreational were older (median 44 vs 37), more often male (79% vs 68%), more often carrying prophylactic ICDs (51.4% vs 26.9%) and beta-blockers (95% vs 65%) — and they took less frequent appropriate and inappropriate shocks during physical activity than the competitive athletes did, with no shock causing death or injury [2]. The young cohort — 129 athletes averaging 16 years, long-QT syndrome the commonest diagnosis, hypertrophic cardiomyopathy second — ran 42 months and shocked 27% of its members with no serious adverse sequelae and lead-malfunction rates comparable to unselected pediatric ICD populations [3]. The review of the era reads the file plainly: participation is possible for most, with individualized counseling on the conditions the registry could not clear [4].

The rule column: from the class-IA ban to programming the athlete's device

The guideline arc is the field's own confession of how wrong the blanket ban was. The 2006 recommendations — the conservative era's consensus on arrhythmias, pacemakers and ICDs in sport — counseled against high-intensity and competitive participation for ICD patients, with pacing-mode caveats for the paced athlete [8]. The problem was never re-litigated by a trial; it was overtaken by data — the registry above — and by the honest observation that patients were exercising anyway, unsupervised and uncounted [4]. The 2015 AHA/ACC Task Force 9 statement rewrote the eligibility file: it became reasonable for athletes with ICDs of any type to participate in competitive sports when free of arrhythmias requiring device therapy for some months, when no underlying condition independently precludes participation, and with the residual fences — trauma to the device, the water, the shock-while-driving class of hazards — priced in shared decision rather than prohibition [5]. The 2020 ESC sports cardiology guideline carries the athletes-with-devices question into the modern frame: sport type and intensity counseled per underlying disease, with the device programmed and followed rather than obeyed as a ban [6]. And the 2021 ESC pacing and CRT guideline owns the paced athlete's half of the door: rate-adaptive programming, sensor selection and follow-up cadence are clinical variables to be tuned to the life the patient actually lives — which for this reader includes the gym [7]. The teaching of the arc for the training reader: the signature that clears the program is the device clinic's, the currency is the underlying condition, and the device itself stopped being a disqualification the year the registry published zero [1][5][6].

The arm column: the kernel, the sling, and what the evidence actually says

This is the door's most practical folklore — "don't raise the arm above the shoulder for a month" — and it deserves the same honest audit as the rest. The kernel is real: Deering and Pederson published two young men whose pacemaker leads fractured in association with weight lifting, and both fractures sat at the same address — crushed between the clavicle and the first rib — the anatomical pinch a heavy overhead pull or a maximal shrug drives right through [9]. A lead is a wire; a wire work-hardened and crushed fatigues; the 1993 report is the mechanism the arm rule protects against, and it is why the rule exists at all [9]. The sling, though, outlived its evidence. The E-MOTION trial randomized 200 patients — 86% pacemakers, 14% ICDs — to mobilization at three hours after implant versus standard immobilization: lead dislodgement at 24 months ran 3% versus 4% (p=0.99), with no major intra-procedural complications and no cost in dislodgement for moving early [10]. The scoping review of everything published on early mobilization after device implant — eight studies, six of them randomized — concluded early mobilization appears safe, that the barrier is the lack of consensus on timing and type rather than evidence of harm, and that an arm support used early is the practical bridge [11]; the 2026 update of the file reads the same direction [12]. The reconciliation the reader should keep: the arm rule was calibrated against a real failure mode at a time when leads, fixation and pocket technique were less forgiving than today's — the modern evidence moved the fence from weeks of sling to graded reintroduction within the implanting center's protocol [9][10][11]. The month of whispering movements is not the standard; nor is day-three heavy overhead pressing. What survives: the fresh implant prices its own protocol, the operated arm ramps back under the center's schedule, and the patient who never asks the clinic what that schedule is, is the one the folklore owns [7][10].

The heart-rate column: when the ceiling is a setting

The paced reader walks into the gym carrying a number most gym-goers never question: his maximum heart rate may be a programmed ceiling, and his sensor-driven "response" is an estimate. The engineering file is honest about this: classic accelerometer-based rate response counts motion — which overspeeds on a shaking leg press and undercounts a smooth grind — while physiological sensors read the body's own signals instead; the impedance-derived contractility sensor delivered improved rate-adaptive pacing during high-intensity exercise precisely where accelerometers misjudge [16], and the technology review of the field maps which sensor class earns which trust in which modality [17]. The clinical file owns the other half: the 2021 ESC pacing guideline treats rate-adaptive programming as a clinical variable tuned to the patient's actual activity — upper sensor rates, slope, and recovery behavior are settings, reviewable at follow-up, and an athlete's settings deserve athlete-level programming [7]. What this means in gym terms: the chest strap that once anchored every zone may now be reading a ceiling someone else chose — so the training anchors move to the ones that never needed a strap: perceived exertion scaled honestly, rep counts, load fractions, breath and recovery between sets — the same RPE-anchored training the beta-blocker file had to rediscover, for the same reason: when the heart-rate channel is owned by hardware or chemistry rather than by the heart's own response, the program needs effort anchors it can trust [7][16][17]. The single highest-yield sentence this reader can bring to his next device follow-up: "I train at these intensities, these modalities, this many hours a week — is my device programmed for that life?" [7]

The training column: the RCT that put ICD patients in rehab

The strongest interventional evidence in this door belongs to a small, honest trial. Fitchet and colleagues randomized 16 ICD patients — average age 58, mostly men — in a crossover design to a 12-week comprehensive cardiac-rehabilitation program versus usual care, then swapped [13]. The results column: exercise time on the treadmill rose 16% (from a mean 9:55 to 11:11, p=0.001) and held for 12 weeks after; hospital anxiety scores fell from 13.4 to 8.1 (p<0.001) and depression scores from 9.9 to 6.7 (p=0.002); and the safety line that prices the whole door: no ventricular arrhythmias and no ICD discharges occurred during the exercise components of the rehabilitation, with total arrhythmia and discharge counts similar before, during and after the program [13]. The file around it agrees: the device-era reviews frame structured exercise as the therapy the ICD patient was routinely denied by fear-based counseling, with the registry supplying the denominator that made supervised exercise ordinary [1][4]. The teaching for the reader: the first six weeks back are not a solo project — a supervised, graded, hospital- or clinic-based reintroduction is the modality the trial tested, the anxiety column it measured is the one this population actually carries, and the discharge count during supervised exercise in the only randomized file this door has was zero [13].

The pool column: the physics that prices the water

Swimming is where the device door stops being about the heart and starts being about the medium. The Zurich correspondence put the physics on the record with a question for a title — salty water stymies shock from an implantable defibrillator? — because water, and especially saline, changes what a defibrillation current does: shunting it away from the chest rather than through it [14]. The drowning arithmetic is the older and simpler column: an athlete who loses consciousness mid-lane does not wait for the device — he waits for the water to stop being in his lungs, and no therapy delivered underwater arrives before that clock runs. The counseling that follows is neither a ban nor a shrug: the swimmer with an ICD and an active arrhythmia file prices the lane with his team — supervised lanes, never alone, never in open water unsupervised — while the paced swimmer with a quiet file usually prices it like anyone else with his condition [5][6][14]. The fence for this door, stated plainly: the pool is not banned; the pool is never swum alone while the file that earned the device is still capable of producing syncope [6][14].

The magnet column: the strongest magnet in the gym is in your pocket

The interference file has quietly rewritten itself around consumer hardware. The review of modern smartphones and their accessories — watch bands, charging magnets, earbuds cases — against pacemakers and defibrillators found the hazard is no longer the treadmill console of old case reports but the magnet arrays riding in daily carry: phones and watches placed directly over the device can trigger magnet mode, suspending anti-tachycardia therapy or altering pacing, which is why the distance rule — keep them off the pocket, not near it — is now standard counseling [15]. In gym terms the column is short and behavioral: phone out of the chest-side jacket pocket before the first set; watch worn on the opposite wrist from the device side is fine for training data, but nothing with a magnet rests on or leans against the pocket — and the old fear of exercise machines interfering with devices belongs to a generation of both that has largely retired [15]. The device clinic's magnet check at follow-up is the audit that catches accidental exposures [7][15].

The honesty column: what the file cannot yet promise

The nulls, stated plainly. The registry is observational, and it enrolled survivors: athletes healthy enough to be exercising with their devices, adjudicated carefully but self-selected — the catastrophic case that discouraged enrollment never reached the registry to be counted [1]. Shocks during sport are common: one athlete in ten took a shock during practice or competition, and eight ventricular episodes delivered multiple shocks — the door clears training; it does not clear the arrhythmia [1]. The randomized file is small: Fitchet's trial — the only RCT of comprehensive rehab in ICD patients this door rests on — crossed over sixteen patients; its zeros are reassuring, its precision is limited [13]. The mobilization trials moved mostly pacemakers: E-MOTION's population was 86% pacemaker, with mostly passive-fixation leads — the fresh ICD and the active-fixion edge cases carry protocol from the implanting center, not from the pooled file [10][11]. No trial ever randomized device patients to competitive sport against prohibition — the guideline change followed data plus honesty about behavior, which is a different epistemic animal [4][5]. And the pacing-sensor literature is engineering-grade, not outcome-grade — sensor trials measure rate delivery, not lives [16][17]. What is not a null: the zero-injury registry endpoints [1], the 3%-vs-4% mobilization dislodgement [10], the zero exercise discharges in the RCT [13], and the guideline arc from ban to programming [5][6][7] — those are counted, and they carry every practical rule below.

The program in gym terms: what stops, what waits, what ramps, what never

Stops and calls emergency services, today: a shock followed by chest pain, breathlessness or fainting — or two shocks in a row without full recovery between them — is the storm script; a single shock ridden out feeling well is a same-week clinic call, not a set-back-on-the-platform event [1][6].

Waits for the protocol: the fresh implant — the first weeks price pocket healing and lead consolidation; the operated arm ramps back on the implanting center's schedule, with the evidence-side reading being graded early movement over the month-long sling [9][10][11].

Waits for the signature: the program's intensity ceiling is owned by the condition that earned the device — the heart-attack, heart-failure, atrial-fibrillation and myocarditis files each carry their own dose rules; the device adds its fences on top of, never instead of, those [5][6].

Ramps and keeps: the aerobic base and moderate resistance work — the modality Fitchet's trial tested with zero discharges and better psychology than the fear script ever delivered [13]; RPE-, rep- and load-anchored programming once the heart-rate channel belongs to the device's settings [7][16][17]; the device follow-up where the athlete's actual training life gets programmed into the ceiling [7].

Never, without the clinic's explicit pricing: solo swimming while the arrhythmia file remains capable of syncope [6][14]; magnets resting on the pocket — the phone in the chest-side jacket, the earbud case tucked against the collarbone [15]; chest-first collision sport with an unpriced pocket [5][6]; and maximal breath-held grinds in the first months of the operated-shoulder calendar, for the lead's sake before the program's [9].

Logs like a device patient, because he is one: the dated ledger — sessions, loads, RPE, any shocks, palpitations or dizziness with their dates — is the single document the device clinic reads best; the patient who walks into follow-up with it gets his program re-priced from data [6][7].

The Brazil anchors: the Chagas pacing door at population scale

The pt-BR twin of this file exists for a Brazilian reader whose health system runs one of the world's largest device programs — and whose pacing file carries a landlord almost no other country has: Chagas disease. The scale anchor: Marcolino and colleagues pulled the public-system ledger — 216,927 cardiac-device implants across SUS over twelve years, annual volume climbing from 14,466 to 20,726 (+43.3%) even as the standardized implantation rate fell from 108.9 to 98.2 per million (−9.8%), with pacemaker rates stable, CRT-D rising, CRT-P falling, and the regional heterogeneity that defines Brazilian access in the file's own conclusions [21]. The access anchor: Leite's case-control from the Brazilian record — 46 Chagas patients pacemaker-implanted against 138 matched Chagas controls — priced the contextual odds of getting a pacemaker at all: larger municipality (OR 3.6), stronger Family Health Strategy coverage (OR 5.3), fewer electrocardiographs per capita (OR 2.6); and over four years of follow-up, the pacemaker did not own the mortality column — only ejection fraction did (32.6% of cases vs 21.2% of controls died, and the device was not the reason) [20]. The defibrillator anchor: CHAGASICS — the Brazilian randomized trial the world's ICD file cites for its hardest population — randomized 323 patients with chronic Chagas cardiomyopathy to ICD versus amiodarone before stopping for administrative reasons at a third of its intended size: all-cause mortality was statistically indistinguishable (38.2% vs 38.6%, HR 0.86), but the ICD arm cut sudden cardiac death, pacing need and heart-failure hospitalizations against the drug — in the disease that kills over ten thousand Brazilians suddenly each year [19]. For the Brazilian reader the practical splice is the same file in his language: the device population is continental, the Chagas pacing door is real and access-shaped, and the high-blood-pressure and heart-failure files own the disease variables the device only watches [19][20][21].

So what do you actually do? The practical file

Six rules, every one sourced from the columns above:

  1. Memorize the shock script before the first set back. One shock felt fine through: stop the session, call the clinic this week. Shock with symptoms, or shocks stacked without recovery: emergency services now — the registry's shocks were survivable; storms are not a training question [1][6].
  2. Let the pocket heal on the center's protocol, not the locker room's. The arm rule protects a real lead-failure mode [9], the sling is out of the evidence [10][11], and the graded ramp belongs to the implanting team's calendar [7].
  3. Program the athlete into the device. Bring the training life — modalities, hours, intensities — to follow-up, and ask whether the rate ceiling, sensor slope and detection settings were written for it; RPE, reps and load become the anchors the strap can no longer be [7][16][17].
  4. Re-enter through supervision when the file is fresh. The only randomized file this door has put ICD patients in structured rehab and measured zero discharges during exercise with anxiety cut in half — the first six weeks back are a program, not a mood [13].
  5. Price the water and the magnets before the barbell. Never swim alone while the arrhythmia file can produce syncope [6][14]; nothing magnetic rides the pocket [15].
  6. Keep the dated ledger. Sessions, RPE, shocks, symptoms, follow-up dates — the document that turns "see how it goes" into a program the clinic can re-price; the device patient's log is a medical record he co-authors [6][7].

How RightRep fits into this

The device file is, at its core, a dose-and-ledger question wearing hardware — a door where the program's anchors (effort, reps, load fractions, dated symptom entries) have to be trustworthy precisely because the heart-rate channel is owned by settings, and where the follow-up consultation reads the patient's own record:

  • The anchors that survive the device. Rep-counted, RPE-scaled, load-fractioned training is exactly the programming the paced and shocked athlete needs when a strap reads a ceiling — the log makes effort auditable without a heartbeat [7][16].
  • The graded return made mechanical. A comeback that records baseline and fraction after fraction is the rehab arc Fitchet tested — structured, progressive, checked — rather than a feeling-based return [13].
  • The symptom ledger beside the training ledger. Shocks, palpitations, dizziness dated beside sessions is the document the device clinic actually reads — the two columns belong in one file [1][6].
  • The aerobic dose counted. The base that the cardiac files price in weekly minutes, counted rather than guessed, is the dose this population trains for [13].
  • The underlying-condition door, honored. The heart-attack and heart-failure programs own the disease dose; the device door only prices the hardware's fences on top of them [5][6].

The bottom line

  • The registry column: 372 athletes with ICDs, median 31 months — zero deaths, zero resuscitated arrests, zero shock-related injuries; shocks 10% in practice vs 6% at rest [1].
  • The splices: recreational athletes shocked less than competitive, no injuries [2]; 129 young athletes, 27% shocked, no serious sequelae, leads no worse than baseline [3].
  • The rule column: 2006's conservative consensus [8] → Task Force 9 2015 clearing stable athletes [5] → ESC 2020/2021 programming the athlete's device instead of grounding him [6][7].
  • The arm column: two weightlifting lead fractures at the clavicle-first-rib crush [9] against E-MOTION's 3-hour mobilization with 24-month dislodgement 3% vs 4% [10] — the sling retired, the graded ramp installed [11][12].
  • The heart-rate column: rate response is engineering — contractility sensing beats accelerometers at intensity [16][17] — so RPE, reps and load become the anchors [7].
  • The training column: the only RCT — rehab raised exercise time 16%, cut anxiety 13.4→8.1, zero discharges during exercise [13].
  • The water and magnet columns: salty water stymies the shock [14] — never swim alone with an unsuppressed arrhythmia file [6]; the phone is a magnet, off the pocket [15].
  • The honesty column: a survivor-enrolled registry, 10% shocked, a 16-patient RCT, and mobilization data from mostly pacemaker populations [1][10][13].
  • The Brazil anchors: 216,927 SUS implants in 12 years [21]; the Chagas pacemaker case-control where access, not the device, set the odds [20]; CHAGASICS — mortality null, sudden death cut [19].
