Consumer wearable technologies to identify and monitor exercise-related arrhythmias in athletes.

ABSTRACT

PURPOSE OF REVIEW The aim of this study was to synthesize the current evidence supporting and against the use of wearable devices to detect underlying heart conditions in athletes and the most significant limitations. RECENT FINDINGS: Although several large studies have been conducted to evaluate the ability of wearables devices to identify atrial fibrillation among the general population, no studies evaluating their ability to detect other exercise-related arrhythmias in athletes are very sparse. Most of the studies or case reports are focused on the wearables' reliability and accuracy compared with standard ECG. Only small studies evaluating the accuracy of one wearable device in athletes have been carried out to date. Unfortunately, none of them have investigated their ability to detect specific arrhythmias in the athletic population. SUMMARY: Rapidly detecting dangerous arrhythmias in a symptomatic athlete continues to be an elusive goal. The use of smartphone ECG monitors can provide diagnostic data in athletes with symptoms that could represent a helpful instrument. However, many uncertainties remain and need to be addressed and validated in large-scale trials to incorporate these devices into the healthcare system and be part of an athlete's daily monitoring and healthcare.
