冠心病是危害人民健康及威胁生命的常见病,应用血管造影检查本病巳累积了不少资料,但毕竟是一种创伤性的诊断技术,而且对随访检查有一定困难。早在一世纪前人们就巳知道心脏收缩间期(简称 STI)可用于判断心室功能,但一直未引起重视,直至1968年 Wei-ssler 等应用无创伤性心功能检查以来无创伤性的诊断技术才逐渐受到临床的重视。七十年代以后这方面的检查又得到进一步的发展。目前无创伤性技术不仅用于诊断也用于判断疗效和预后,其中左室收缩间期(STI)首先在临床上应用。本文采用心电图、心音图、颈动
Coronary heart disease is a common disease that endangers people’s health and life-threatening diseases. The application of angiography has accumulated a lot of information about this disease, but it is a traumatic diagnostic technique after all, and there are some difficulties in follow-up examination. As early as a century ago, people knew that the systolic interval (referred to as STI) can be used to determine ventricular function, but has not been valued until Wei-ssler and other non-invasive cardiac function tests in 1968 non-invasive diagnostic techniques Only gradually by the clinical attention. In the seventies this inspection has been further developed. At present, non-invasive technique is not only used for diagnosis but also for judging curative effect and prognosis. The systolic left ventricular (STI) is the first clinical application. In this paper, ECG, phonocardiogram, carotid artery
