The electrocardiograms and the clinical features of the subjects, 1686 males and 540 females, examined in the Health Science Center from April 1, 1976 to March 31, 1977, were analysed. The ECGs were classified according to our modification of the Minnesota Code. The abnormal ECGs were found in 434 subjects. The relationship between the ECG findings and the clinical features was observed as follows. (1) Age: The frequency of abnormal q or poor progression of r, ST segment depression, T wave flatness, and conduction disturbance were observed oftener with the increase in age, but the incidence of both sinus tachycardia and bradycardia did not show any significant relation to the age. (2) Sex: S_<V1>+R_<V5>35mm and R_<V5>26mm, and AV blockof first degree were found more frequently among males, but ST segment depression and T flatness were found more commonly among females. (3) Hypertension: Those who had hypertension were found more frequently in the group of S_<V1>+R_<V5>35mm with R_<V5>26mm, and ST depression, especially among men in their forties. The mean of systolic as well as diastolic blood pressure in the group of S_<V1>+R_<V5>≧40mm with R_<V5>≧30mm, and the mean of diastolic blood pressure in the group of ST depression more than 1mm, were higher than those in any other group. (4) Arteriosclerosis: Arteriosclerosis of the eye ground was found more frequently with the statistical significance in the abnormal ECG group more than in the normal ECG group. Furthermore, arteriosclerosis was more frequently observed in the groups of abnormal q or poor progression of r, S_<Vl>+R_<V5>≧40mm with R_<V5>≧30mm, and ST depression, and was less in the groups of RBBB and incomplete RBBB. (5) Correlation of the findings of ECG, blood pressure and ocular fundus: Presence or absence of the arteriosclerosis suggested by the clinical examination was more related to blood pressure than changes in the ECG. (6) Subjective symptoms: Subjective symptoms were more frequently found in the groups of abnormal q or poor progression of r, ST-T change, conduction disturbance and arrhythmia. On the contrary, they were found less in the groups of RBBB, incomplete RBBB and bifascicular block. The subjective symptoms were palpitation, dyspnea, precordial pain and feeling of disordered heart beat, however, there existed not always a significant relation between each of the subjective symptom and each of the abnormal ECG.
