CRT电极经房间隔穿刺植入左室心内膜起搏心电图1例

A case of Transseptal endocardial left ventricular pacing for cardiac resynchronization therapy electrocardiogram

将左室电极行房间隔穿刺植入左室内膜,对1例完全性左束支传导阻滞患者进行同步化治疗。常规心电图示Ⅰ导联主波为负向波,Ⅱ、Ⅲ、AVF呈R型,V1导联呈rS型,QRS时限进一步缩小为0.12s,心电图诊断为窦性心律,双心室起搏,心电图各导联QRS形态和时限具有一定的特征,行心内膜起搏的CRT患者的心电图分析具有重要价值。

The left ventricle electrode was implanted into atrial septal puncture,with complete left bundle branch block patients for cardiac resynchronization therapy （ CRT ） .The electrocardiogram I lead showed main wave negative wave, II,III,AVF is R,V1 lead was rS type, QRS duration further reduced to 0.12s,ECG diagnosis of sinus rhythm,biventricular pacing, electrocardiogram of the lead QRS morphology and time have certain characteristics for cardiac pacing in patients with CRT.The analysis of ECG is of great value.
