Abstract

Abstract: Belt-type ambulatory electrocardiograph (EV-201) is an arrhythmia diagnostic device that can record an electrocardiogram (ECG) for a maximum of 2 weeks. Here, we report the novel utility of EV-201 in detecting arrhythmias in two professional athletes. Treadmill exercise test and Holter ECG failed to detect arrhythmia because of insufficient exercise, electrocardiogram noise. However, by wearing EV-201 only during a marathon run, supraventricular tachycardia onset and termination were successfully detected. Throughout, both athletes were diagnosed with fast–slow atrioventricular nodal re-entrant tachycardia. Therefore, EV-201 enables long-term belt-type recording, thereby being useful in detecting tachyarrhythmias that occur infrequently and during strenuous exercises. Learning objective: Diagnosis of arrhythmias during high-intensity exercise in athletes by conventional electrocardiography is sometimes difficult due to inducibility and frequency of arrythmias or motion artifacts. The primary finding of this report is that EV-201 is useful in diagnosing such arrhythmias. The secondary finding is that fast-slow atrioventricular nodal re-entrant tachycardia is a common occurrence in arrhythmias among athletes.
