本文利用心阻抗微分图(ICG)和颈动脉搏动图(CPT)对左前分支阻滞(LAH)和完全性右束支阻滞(RBBB)患者进行左心功能测定。用ICG检查发现LAH组和RBBB组的Q—Z间期比正常组明显延长,HI指数降低,QZ/BX比值增大,CPT法测定中LAH和RBBB两组中Q—S、LVET、QU/LVET的比值有显著差异。
In this paper, left ventricular function (LAH) and complete right bundle branch block (RBBB) were measured in left ventricular function using cardiac impedance differential graph (ICG) and carotid artery pulsation diagram (CPT). ICG examination showed that the Q-Z interval in LAH group and RBBB group was significantly longer than that in normal group, the HI index was decreased and the ratio of QZ / BX was increased. The Q-S, LVET, QU / LVET ratio significantly different.
