作者采用二维M-超声心动图检查了高血压和/或肥胖者的心脏结构和收缩、舒张功能,以分析肥胖和高血压对左心室充盈的影响。研究对象为无肥胖组(体重指数≤26kg/m~2)和轻度-中度肥胖组(体重指数>26kg/m~2<35kg/m~2),每组均包含血压正常者13例,轻度-中度高血压者41例,两组年龄,性别和动脉血压均相似。除外继发高血压,至少研究前四周停服各种药物。用东芝SSA-60A超声仪连扫描器,探头为2.5MH_2或3.75MH_2患者休息≥10min,待血压、心率稳定后,取略偏左侧卧位,在记录超声心动图同时,测定血压。超声探头位于第二或第四肋间隙,采用标准方法,记录左室超声图象。以心电图R波顶点和室间隔运动最低点作为左室舒张,收缩末径,计算早期峰充盈率和快速充盈时间。按照penn方法,除外心内膜回声厚度,计算室壁厚度,超声心动图记
The authors examined cardiac structure and systolic and diastolic function in hypertensive and / or obese subjects using two-dimensional M-echocardiography to analyze the effects of obesity and hypertension on left ventricular filling. The subjects were non-obese (body mass index ≤26kg / m ~ 2) and mild-moderate obesity (body mass index> 26kg / m ~ 2 <35kg / m ~ 2) , Mild to moderate hypertension in 41 cases, two groups of age, gender and arterial blood pressure were similar. Except for secondary hypertension, at least the first four weeks of study stopped taking various drugs. With Toshiba SSA-60A ultrasound scanner, the probe is 2.5MH_2 or 3.75MH_2 patients resting ≥ 10min, until the blood pressure, heart rate stabilized, take a slightly left lateral position, while recording echocardiography at the same time, the determination of blood pressure. Ultrasound probe is located in the second or fourth intercostal space, using standard methods to record left ventricular ultrasound images. The peak of R wave and the lowest point of interventricular septum were taken as the left ventricular diastolic and systolic diameters, and the early peak filling rate and fast filling time were calculated. In accordance with the penn method, except for endocardial echo thickness, wall thickness calculation, echocardiography
