心脏收缩时间间期(STI)是估价左心功能的一种方法。作者近两年来对23例心脏手术病人进行了手术前后STI的比较,现将结果介绍如下: 病人经确诊后进行心脏手术治疗,手术前及手术后1—2月内进行STI检查及对比。所用仪器为上海XD—30B三导同步心电图机,测颈动脉搏动图、心音图,心电图,分别测总电机械收缩期(Q-S_2),即由心电图QRS波群起点测劲心音图第二心音的主动脉瓣成分;左室喷射时间(LVET),即由
Systolic time interval (STI) is a method of evaluating left ventricular function. In the past two years, the authors compared the STI of 23 patients undergoing cardiac surgery before and after surgery. The results are as follows: The patients underwent cardiac surgery after being diagnosed, STI examination and comparison within 1-2 months after surgery and before surgery. The instrument used for the Shanghai XD-30B three-lead synchronous ECG machine, measuring the carotid artery pulsation diagram, phonocardiogram, ECG, were measured total electromechanical systolic (Q-S_2), that is, Heart aortic valve component; left ventricular ejection time (LVET), that by
