大量研究表明,体位变换对人体血液动力学具有明显影响。但这种影响在正常人和心脏病人中有何异同则报道尚少。1980年以来,我们分别对40名正常人和54名心脏病人的心率(HR)和心脏指数(CI)的体位影响进行了观察和比较,初步看出,上述指标对体位改变的异常反应与左心室功能障碍有关。兹将结果报告如下: 对象和方法一、对象:正常组。40例,男性32例,女性8例。平均年令:51.6±0.9岁(X±SE)(41～66岁)。全部受试者经详询病史,体格检查,胸透或胸片、血压和血清脂类分析,心电图及马氏双倍运动试验等检查均正常者,并进行心缩间期测定(简称“STI”),PEP/LVET均小于0.40,其平均值±标准误为0.360±0.007。
Numerous studies have shown that body position changes have a significant effect on human hemodynamics. However, there are few reports on the similarities and differences of this kind of effect between normal and heart patients. Since 1980, we observed and compared the body position of heart rate (HR) and cardiac index (CI) of 40 normal subjects and 54 cardiac patients respectively. We initially found that the abnormal response of the above indexes to the changes of body position and left Ventricular dysfunction related. The results will be reported as follows: objects and methods A, object: normal group. 40 cases, 32 males and 8 females. The average annual order: 51.6 ± 0.9 years old (X ± SE) (41 ~ 66 years old). All subjects underwent detailed examination of history, physical examination, chest X-ray or chest radiography, blood pressure and serum lipid analysis, electrocardiogram and Markov double exercise test and other tests were normal, and the determination of systolic phase (referred to as “STI ”), PEP / LVET is less than 0.40, the average ± standard error of 0.360 ± 0.007.
