老年高血压病静息状态心缩时相分析

ANALYSIS OF SYSTOLIC TIME INTERVAL IN AGED HYPERTENSIVE PATIENTS AT REST

本文对40例老年高血压病人及相关对照进行静息状态下心缩时间间期测定。对年龄、性别、病程、心率、收缩压、舒张压、平均动脉压、总电机械收缩时间(QS_2I),射血前期(PEPI)、左室射血时间(LVETI)及(PEP/LVET)之比,11项指标进行了统计学分析。认为心缩时间间期可在心电图、胸部X线、M型超声心动图发现左心室肥厚前证实高血压病人左心功能已有损害。

Systolic time interval in 40 aged hypertensive patients were determined at rest.Statistical analyses of 11 indices, including age, sex, course of the disease, heart rate, systolic pressure, diastolic pressure, average arterial pressure, QS2I, PEPI, LVETI and PEP/LVET, were made.It was shown that impaired function of the left ventricle in hypertensive patients might be confirmed with STI before hypertrophy of the left ventricle was being discovered through ECG,X-ray examination of the chest and M-type UCG.Functional impairment of the left ventricle in aged hypertensive patients in the early period was more serious than that in the adult hypertensve patients Hyperten-ion of the common type (with mainly elevation of systolic pressure) in the aged was similarly harmful, therefore enough attention should be paid to as well.
