Best Practice Case Studies-Case 117 Asset 3 Expert Consensus: Arrhythmias in the Athlete

Pdf Summary

The 2024 HRS expert consensus statement provides detailed guidance on evaluating, treating, and managing arrhythmias in athletes of all ages, with the main goal of enabling safe return to sport whenever possible. It emphasizes that sports restriction can cause real physical and psychological harm, so decisions should be individualized and based on disease-specific risk assessment plus shared decision-making.<br /><br />Key themes include:<br />- Athletes with arrhythmic conditions should be evaluated by clinicians familiar with exercise-related cardiac adaptation and “grey zone” findings.<br />- Exercise stress testing should mimic the athlete’s sport and be carried to maximal effort, not stopped at an arbitrary heart-rate target.<br />- Emergency action plans, immediate CPR, and rapid defibrillation are essential at all athletic venues.<br /><br />The document reviews major conditions relevant to athletes:<br />- Sudden cardiac arrest: rare in young athletes but risk rises with age and varies by sex, race, and sport. Common causes differ by age, with inherited/electrical disease more common in the young and coronary disease more common in older athletes.<br />- Commotio cordis: rare, preventable blunt chest trauma causing VF; chest protectors and safety balls may reduce risk.<br />- Syncope and palpitations: most cases are benign, but exertional syncope requires careful workup to exclude dangerous cardiac causes.<br />- Ventricular arrhythmias: benign PVCs may only need observation or symptom control, while complex arrhythmias require imaging, exercise testing, and sometimes ablation or ICDs.<br />- Inherited arrhythmia syndromes and cardiomyopathies: athletes with LQTS, CPVT, Brugada, HCM, ACM/ARVC, and DCM may sometimes return to play after expert assessment, appropriate treatment, and ongoing follow-up.<br />- Atrial fibrillation: more common in endurance athletes; management includes risk-factor modification, anticoagulation when indicated, and often catheter ablation.<br />- Wolff-Parkinson-White: athletes should generally return to play pending expert evaluation; ablation is often recommended, especially when symptoms or high-risk features are present.<br />- Bradycardia and pacemakers: training-related bradycardia is often normal, but significant conduction disease needs evaluation; device type and programming should support athletic performance.<br /><br />The statement also highlights future research gaps, especially regarding women athletes, performance-enhancing drugs, wearables, and long-term return-to-play outcomes.
