Does an electrophysiological study aid in risk stratification for endurance athletes with ventricular arrhythmias?
An electrophysiological study is indicated for risk stratification in endurance athletes with complex ventricular arrhythmias due to a high prevalence of underlying right ventricular involvement.
Complex ventricular arrhythmias do not necessarily represent a benign finding in endurance athletes. An electrophysiological study is indicated for risk evaluation, both by defining inducibility and identifying the arrhythmogenic mechanism. Endurance athletes with arrhythmias have a high prevalence of right ventricular structural and/or arrhythmic involvement. Endurance sports seems to be related to the development and/or progression of the underlying arrhythmogenic substrate.
Hein Heidbüchel (2003) studied this question.
