[Echo- and electrocardiographic signs of different forms of hypertrophic cardiomyopathy].

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.
