为了阐明仰卧位时需氧量减少的机制,本文从运动能量学、运动时氧的利用的心血管反应的观点进行了研究。方法:(1)病人选择。受试者为14例冠心病人(男12,女2,平均年龄58±8岁),其中6例患心绞痛、8例有陈旧性心肌梗塞。所有病人经冠状动脉造影有明显冠状动脉狭窄,平均左室射血分数57±9%(36～67%),在试验前10天内做常规平板 In order to elucidate the mechanism of reduced oxygen demand in the supine position, the present study was conducted from the viewpoints of kinetic energy and cardiovascular responses to the use of oxygen during exercise. Methods: (1) Patient selection. Subjects were 14 patients with coronary heart disease (male 12, female 2, mean age 58 ± 8 years), of whom 6 had angina and 8 had old myocardial infarction. All patients had obvious coronary artery stenosis by coronary angiography, the average left ventricular ejection fraction 57 ± 9% (36 ~ 67%), 10 days before the test to do conventional plate
