本文采用心阻抗图(ICG)和颈动脉搏动图(CPT)两种方法,测定了正常人与冠心病患者的左室收缩时间间期(STI),并分析这些指标与冠心病的关系。在正常组和冠心病组之间,除HR差异不显著外,其余各项指标均有显著差异(P<0.01)。两种不同方法测定同一指标的值,二者相差不显著(P>0.05)。两种方法均证明冠心病人的左心功能不同程度的减退,因此,我们认为ICG法的Q—B间期、B—X间期及QB/BX比值与CPT法的PEP、LVET、PEP/LVET比值一样是评定左心功能可靠而敏感的指标。
In this paper, ICG and CPT were used to measure the left ventricular systolic time (STI) between normal subjects and patients with coronary heart disease, and the relationship between them and coronary heart disease was analyzed. In the normal group and coronary heart disease group, except for the difference of HR was not significant, the rest of the indicators were significantly different (P <0.01). Two different methods to determine the value of the same index, the difference was insignificant (P> 0.05). Therefore, we think that the Q-B interval, B-X interval and QB / BX ratio in ICG method are significantly different from those in CPT, PEP, LVET and PEP / The LVET ratio is a reliable and sensitive measure of left ventricular function.
