Objective To discuss the prevention of atrioventricular block during radio_frequency ablation (RFCA) for the treatment of atrioventricular nodal reentrant tachycardia (AVNRT).
探讨房室旁道(简称房道)和房室结双径引起的折返性心动过速的初次发病年龄。
The initial onset age of reentry tachycardia induced by atrioventricular accessory pathway and dual atrioventricular nodal pathways was investigated.
目的：为探讨心传导系房室结区双（多）径路传导、折返等复杂电生理的形态学基础。
Ohjective: To study the morphological aspects corresponding to the complex electrophysiological signs of dual (multi) -pathway and reentry of the atrioventricular node (AVN) area.
