[Arrhythmias in patients with mitral valve prolapse].

The aim of the study was to analyse rhythm disturbances in 92 patients with mitral valve prolapse syndrome (52 women and 40 men). The patients were examined by resting electrocardiograms monitoring, exercise electrocardiogram (submaximal exercise test), phonocardiograms and echocardiograms. We found tachycardia sinusalis in 72 patients (78%), supraventricular premature beats in 23 (25%) and ventricular premature beats in 54 patients (59%). There was no correlation between dizziness and syncope and ventricular rhythm disturbances in those patients.
