[Prevalence of hyperkinetic ventricular arrhythmias in an ambulatory population of nonprofessional athletes. A study controlled by ambulatory electrocardiography].

Hyperkinetic ventricular arrhythmia being the main cause of electrical destabilization and hence fatal tachy-arrhythmias, we have studied, by Holter test, the prevalence of these arrhythmias in ambulatory non-professional athletes and compared it with a homogeneous group of sedentary subjects in order to evaluate if sports, even if not in athletic competitions, represent a potential risk for sudden death. The results show the prevalence of hyperkinetic ventricular arrhythmias to be similar in the two groups and not related to sports.
