[The analysis of the result of the medical examination of inhabitants in the Honjoh area--the relationship between the abnormality in the electrocardiogram and blood pressure, age].
Blood pressure and electrocardiographic findings obtained from the medical screening of citizen (total 834) in Honjyo area, which was done in University of Occupational and Environmental Health Hospital from 1979 to 1983, were analysed. The findings of electrocardiograms (ECG) were classified according to Minnesota code. In this study, the prevalence of Hypertension, classified by the criteria of WHO, showed 12.2% in total, which was lesser than that of Japanese (23.1%). On the electrocardiographic findings, left ventricular hypertrophy and myocardial abnormalities in hypertensive group were significantly higher when compared to those of normotensive group. The ratio of abnormal ECG group was slightly higher than that of Japanese. Especially, the prevalences of arrhythmia and ST elevation were significantly higher than those of Japanese. And there were significant correlations between LVH and blood pressure, and between the abnormalities of conduction system and age. However, it is very difficult to conclude whether these findings are characteristic feature in Honjyo area or not. In order to clarify the characteristic features of cardiovascular systemic abnormalities in Honjyo area, the analysis of more cases would be needed.
