证明有症状的心动过速患者存在结室附加束(NVF)是困难的,他需要详细的电生理检查。本文旨在究究NYF的心电图(ECG)特征。方法:电生理研究的87人用12导ECG和心腔内多极导管同步记录观察窦性心律、心动过速、超速抑制及不应期的测定。多极导管还用于右房、冠状窦、His束、右室起搏和左、右房室沟的标测。全部病人有左束支传导阻滞(LBBB)形态
It is difficult to demonstrate the presence of additional compartment bundle (NVF) in symptomatic tachycardia patients and he needs a detailed electrophysiological examination. This article aims to investigate the electrocardiographic (ECG) characteristics of NYF. Methods: Eighty-seven electrophysiological studies were performed to observe sinus rhythm, tachycardia, hyperstimulation, and refractory period using a 12-lead ECG and an intracardiac multi-pole catheter. Multipolar catheters are also used for the right atrium, coronary sinus, His bundle, right ventricular pacing and left and right atrioventricular groove mapping. All patients had left bundle branch block (LBBB) morphology
