心脏阻抗图是一种无损伤性方法,且可重复测量,因而此法对评定缺血性心脏病病人的左室功能是有价值的。本研究用此法对35例具有或不具有心房颈动脉旁路的缺血性心脏病病人和用微型球形乳剂闭塞多条冠状动脉的5支狗进行观察。其结果如下:心脏指数从运动开始即较休息时 Cardiac impedance map is a non-invasive method, and can be repeated measurements, so this method for the assessment of left ventricular function in patients with ischemic heart disease is valuable. In this study, 35 patients with ischemic heart disease with and without atrial carotid artery bypass and 5 dogs with multiple coronary arteries occluded with micro-spherical emulsions were observed in this study. The results are as follows: Heart index from the beginning of exercise that is more than rest
