原发高血压对右室功能的影响尚不清楚,本文采用脉冲多普勒超声心动图研究了高血压患者的右室舒张功能。研究的50例轻度原发高血压患者均为男性,舒张压12.7～14.5KPa(95～109mmHg),除外各种心脏病,肺部疾病,胰岛素依赖性糖尿病等,检查前2周停用降压药,对照组10例无心脏病,血压正常,年龄与高血压组相仿。全部患者均进行了M型和二维超声心动图检查。多普勒取样标本置于三尖瓣环下方瓣叶之间,尽量使多普勒声束与血流方向一致(角度接近0)。流入速度曲线以100mm/S记录在录像带上。应用计算机分析5个心动周期流速曲线,计算早期迅速充盈(E)及晚期充盈速度(A)及其比率,1/2加速和1/2减速时间.
The effect of primary hypertension on right ventricular function is not clear, this paper uses pulsed Doppler echocardiography to study the right ventricular diastolic function in hypertensive patients. 50 patients with mild primary hypertension were male, diastolic blood pressure 12.7 ~ 14.5KPa (95 ~ 109mmHg), except for a variety of heart disease, lung disease, insulin-dependent diabetes mellitus, check out 2 weeks before the drop Pressure medicine, the control group of 10 patients without heart disease, normal blood pressure, age and hypertension group similar. All patients underwent M-mode and two-dimensional echocardiography. Doppler sampling specimens placed in the valve under the tricuspid annulus, try to make the Doppler beam and blood flow in the same direction (angle close to 0). The inflow velocity curve is recorded on the tape at 100 mm / s. Five cardiogram cycles were analyzed by computer, and the early rapid filling (E) and late filling speed (A) and their ratios, 1/2 acceleration and 1/2 deceleration time were calculated.
