[Heart rhythm disorders in mitral valve prolapse syndrome and their treatment].

Sixty-three patients with the mitral prolapse (MP) syndrome and a variety of heart rhythm disorders were studied. Diagnostic signs of MP and arrhythmias associated with this conditions are discussed. The most common heart rhythm and conductivity disorders encountered were ventricular extrasystoles (in 27 patients) and paroxysmal atrial fibrillation (in 13). The mechanisms of cardiac arrhythmias and blocks, and principles of their treatment in patients with the MP syndrome are discussed.
