近年来应用无创性方法测定冠心病患者的心脏收缩间期(STI)已相当多,但对其舒张间期(DTI)的测定报告甚少。本文旨在以阻抗法及 ACG 法测定冠心病患者的 DTI,并结合文献探讨其对冠心病的诊断价值。为了获得“单纯的”左心室阻抗图形,我们采用左心室阻抗微分图法代替一般习用心前区阻抗微分图,并与正常人作对照,现将结果报告如下。 In recent years, the application of noninvasive methods for the determination of coronary heart disease in patients with heart systolic interval (STI) has been quite a lot, but its measurement of diastolic interval (DTI) is rarely reported. The purpose of this article is to determine the DTI of patients with coronary heart disease by impedance method and ACG method, and to explore its diagnostic value of coronary heart disease. In order to obtain a “simple” left ventricular impedance graph, we use the left ventricular impedance differential graph instead of the conventional precordial impedance differential graph, and compared with normal people, the results are reported as follows.
