RESUMEN
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.

Twenty-six patients with idiopathic and secondary hypertrophic cardiomyopathies were examined. The diagnostic value of echo- and electrocardiographic signs of hypertrophic cardiomyopathy is discussed, the more important among those being the thickness and shape of the interventricular septum, anterosystolic movement of the anterior cusp of the mitral valve, electrocardiographic evidence of left-ventricular hypertrophy and left-atrial changes, abnormal Q waves.
