Abstract

The duration of the phases of left ventricular systole was measured from simultaneous recordings of the electrocardiogram, phonocardiogram and carotid arterial pulse tracing using a multichannel photographic system with paper speed at 100 mm per second. Observations were made in 81 male and 66 female patients with hypertension and 41 healthy males and 38 healthy females who served as controls. All hypertension patients were classified by change in funduscopic finding, EKG and grade of diastolic pressure. STI were measured in each group and analysed. The resutls were as follows: 1. The normal PEP/LVET was 0.293 in male and 0.303 in female. 2. In male & female hypertensive patients, all STI were significantly difference to that of normal control except QA2. 3. In male hypertensive patients, the degree of EKG, funduscopic change and diastolic pressure were positive relation to the increase of PEP/LVET.
