Abstract

The present paper deals with the relationship among the findings of ECG, blood pressures and ocular f undi of the inhabitants of age 40 and over in the inland farm and the coastal fishing villages of the different mortalities from cerebrovascular lesions. The results follow: 1) Blood pressure levels were significantly higher for inhabitants in the farm village, for male in systolic (P<0.01) and for female in diastolic (P<0.02). 2) Prevalence of hypertensive changes in ocular f undi was high in the fishing village, whereas that of the sclerotic changes was higher in the farm village, and the differences were both significant. 3) Frequency of the abnormal ECG findings, as of the final classification code, high voltage code, ST change code and T change code were higher for hypertension group compared with those of normotension and borderline groups. 4) Prevalence of the higher degree changes of the findings of ocular fundi of both hypertensive and sclerotic (H2-4 and S2-4) were high for the hypertension group. 5) Complication of the abnormalities of hypertension, changes of ocular fundi and ECG findings was higher for the farm villagers compared with that of the fishing villagers.
