由于听到或记录到第四心音(以下简称为S_4)是简便易行的无创伤性的诊断方法,故近年来日益广泛地受到临床工作者的重视。它对于冠心病诊断的评价,迄今尚无定论。有的认为若未听到S_4,则冠心病的诊断是靠不住的。有的认为在无心血管疾病的人群中,也可以听到S_4而且S_4的发生率随着年龄的增长而升高。本文就我们从1978年1月至同年12月冠心病门诊患者与年龄相仿但无明显心脏病者各50例均进行心音图记录,现比较分析如下。
Since hearing or recording the fourth heart sound (hereinafter referred to as S_4) is a simple and easy-to-use noninvasive diagnostic method, it has been increasingly recognized by clinicians in recent years. Its evaluation of the diagnosis of coronary heart disease, so far no conclusive. Some believe that if not heard S_4, then the diagnosis of coronary heart disease is unreliable.
