收缩时间间期(STI)是目前较为实用的无创伤性定量测定心脏功能的方法,其测定结果与冠脉造影的检查结果相一致,又与直接测定的血液动力学变化有很好的相关性。我们利用同步记录心电图,心音图和颈动脉搏动图的方法,对70例老年冠心病患者(60岁以上),进行STI测淀,并与正常老年组(60岁以上),老年前期组(45—
The time to systole (STI) is currently a more pragmatic, noninvasive, quantitative method of determining cardiac function. The results of the STI are consistent with those of coronary angiography and have a good correlation with directly measured hemodynamic changes . 70 patients with coronary heart disease (over 60 years of age) were examined by STI, and compared with the normal elderly group (over 60 years old), the elderly group (45 -
