摘要
器质性心脏病瘢痕相关性室性心动过速(室速)的发生主要是折返机制,目前多采用心脏三维标测系统指引下对耐受性好、血流动力学稳定的室速激动标测消融,对于血流动力学不稳定的室速,窦性心律下基质标测、电压图判断室速的解剖基质,结合起搏标测和拖带标测技术识别室速的折返环,盐水灌注导管消融治疗;近年来不断积累有关临床循证证据、适应证进一步拓展、新的标测消融和辅助技术临床上应用,取得了新的进展。
The mechanism of ventricular tachycardia（VT） in organic heart disease is reentry within the scar and scar-border zone.Three dimensional mapping systems are often helpful for mapping,and irrigated ablation catheters are essential for linear ablation.Several mapping strategies are helpful in the scar-related VT.Activation mapping for hemodynamically tolerated VT,substrate mapping and voltage mapping for unstable VT,pace mapping and entrainment mapping determine putative VT exit sites and channels of slow conduction.We review the development of evidence-based medicine,indication,mapping,ablation and support methods for catheter ablation in scar-related VT.
