The cardinal presenting symptoms were dyspnea, chest pain and palpitation in the order of decreasing frequency. Physical examination revealed apical systolic murmur in 27 cjases (90%), with thrill in 10 (33%), and the routine chest films showed enlargment of cardiac silhouette in 15 cases (50%). Abnormal electrocardiographic findings are noted in 27 cases (90%). Among them repolarization abormalities and left ventricular hypertrophy were the most common, occurring in 71% and 66 % of the cases, respectively, follower1 by left atrial enlargment in 24% and the abnormal Q waves in 20% Among various echocardiographic abnormalities, the mean of septal thickness and its ratio to left ventricular posterior wall thickness were 19 mm and 2,1 respectively, and the mean of the degree of systolic anterior motion of mitral valves was 9 mm. The mean of preejection period and left ventricular ejection time as well as their ratio determined in 10 cases were within normal limits.
