心脏收缩间期(STI),是近10多年发展起来的一种无创伤性心脏功能检查方法。本文测定了44例冠心病人的STI,并与40例健康成人作对照,对其几项主要测值的敏感性及其与心脏结构病变程度的关系,进行了初步分析。冠心病人又以超声心动图心内结构病变的不同程度分为两组:冠心I组(重度病变组)
Systolic heart cycle (STI), is a non-invasive cardiac function test developed in the past 10 years. In this paper, we measured the STI of 44 patients with coronary heart disease and compared them with 40 healthy adults. The sensitivity of several major measurements and their relationship with the severity of cardiac structural changes were analyzed. Coronary heart disease patients and intracardiac echocardiography structural lesions of varying degrees are divided into two groups: coronary heart I group (severe lesions group)
