[Ventricular pre-excitation syndrome in adolescents].

A total of 26 adolescents (aged 14-18) with the premature ventricular exitement (PVE) syndrome were under observation, 17 of them being followed up in the time course of 2 to 10 years. The LGL syndrome and Maheim type were rather often noted among such adolescents. Paroxysmal tachycardia attacks and in some cases extrasystole were recorded in 34% of the patients with the PVE syndrome. Bicycle ergometry evidenced a decrease in the functional capacity of the cardiovascular system of the adolescents with the PVE syndrome.
