Sport Participation in Patients with Implantable Cardioverter-Defibrillators.

Abstract

Athletes diagnosed with cardiovascular disease may receive implantable cardioverter defibrillators (ICDs). Until recently, there were no data describing the safety of return to play for athletes receiving an ICD, and consensus recommendations restricted ICD patients to competitive sports no more vigorous than bowling or golf. The ICD Sports Registry prospectively followed 440 athletes who continued sports participation after receiving an ICD, for up to 4years. While many received shocks, both appropriate and inappropriate, during competition or practice, as well as during other physical activity or rest, there were no failures to defibrillate and no injuries related to arrhythmia or shock during sports. Recent subanalyses as described below have focused on how best to program the ICD, and on the younger subgroup including interscholastic athletes. Based on these data, the most recent consensus statement from the AHA/ACC on athletic eligibility now describes sports participation with an ICD as a IIB recommendation, "may be considered".
