In order to detect heart diseases in adults by the use of more precise modern cardiological methods,the following three different kinds of studies were performed:Group (Gr.)I ;computer assisted and non-computer electrocardiograph (ECG)analyzed in 70,524 and 16,153 healthy subjects, respectively,Gr. II ;echocardiography, radionuclide and cardiac catheterization examination in 537 subjects with abnormal ECG, Gr. III ; endomyocardial biopsy analysis of 103 cases.In Gr.I,four cases out of the 16,153 healthy subjects were found to have a coved type ECG pattern suggesting Brugada syndrome. In Gr. II, coronary artery disease (n＝18; 3.4%), valvular heart disease (n＝22; 5.4%), hypertrophic cardiomyopathy (n＝29 ; 5.4%), dilated cardiomyopathy(n＝4;0.8%),electric disturbance type of cardiomyopathy(n＝2;0.4%),corrected transposition of great arteries (n＝1; 0.2%) and nine other heart diseases were detected. Six cases underwent cardiac surgery or coronary intervention. Gr. III analysis revealed that apparent cardiomyopathic disease showed giant negative T wave 82% (16/27subjects), left ventricula hypertrophy 67% (8/12),abnormal Q wave 75% (6/8)and left bundle branch block pattern 60% (3/5).In particular,two cases of Fabry’s disease were detected. We conclude that, in addition to coronary artery disease, cardiomyopathies should be considered when we encounter abnormal ECG.We were able to detect them in 30～40% of the cases.
