室性心动过速尤其是器质性室性心动过速和心房纤颤为2大严重心律失常。心房纤颤导管消融临床应用较多,而器质性室性心动过速尤其是血流动力学不稳定室性心动过速和直接导致猝死的心室颤动等恶性室性心律失常的导管消融方面的进展较慢,这很大程度上是因有埋藏式心脏复律除颤器作为首选,同时有伦理和法律方面原因,本文就恶性室性心律失常导管消融现状做一概述。 Ventricular tachycardia, especially organic ventricular tachycardia and atrial fibrillation, are two major arrhythmias. Atrial fibrillation catheter ablation clinically used more, and organic ventricular tachycardia, especially hemodynamic unstable ventricular tachycardia and sudden death caused by ventricular fibrillation and other malignant ventricular arrhythmia catheter ablation Progress is slow, largely due to the first choice of an ambulatory cardioverter defibrillator with ethical and legal reasons. This review summarizes the status of catheter ablation of malignant ventricular arrhythmias.
