患者,女,80岁。诊为冠心病。偶有晕厥,劝其安装起搏器被拒绝,而后自动出院. 本文心电图第二、三两行是V_1导联连续记录。基本心律为窦性,P-P匀齐,心房率约97次/分。心室率缓慢,QRS形态多变,V_(1α)起始处及V1.b后段QRS呈CRBBB型,与P波呈阻滞性分离状态,其余处多呈房室2:1传导。对照梯形图分析V_1导联,V1a的R_3是完全性心室夺获,呈CLBBB型,R_4为不全性心室夺获,呈ICLBBB型,R_5则为“正常化”室性融合波,即室性逸搏冲动和窦性夺获冲动分别
Patient, female, 80 years old. Diagnosed as coronary heart disease. Occasional fainting, advised to install the pacemaker was rejected, and then discharged automatically.This ECG second and third lines are V_1 lead continuous record. The basic rhythm of sinus, P-P uniform, atrial rate of about 97 beats / min. The ventricular rate was slow and the QRS morphology was changeable. The QRS at the beginning of V_ (1α) and the posterior segment of V1.b was CRBBB type, which was separated from the P wave in a hysteroskedasticity. The rest were mostly atrioventricular 2: 1 conduction. Control ladder analysis of V_1 lead, V1a of R_3 is a complete ventricular seizure, was CLBBB type, R_4 was incomplete ventricular seizure, was ICLBBB type, R_5 is “normalized” room fusion wave, that is, Impulsive stroke and sinus impulse respectively
