室性心律失常是心脏性猝死的一个重要原因,近几年来随着对室性心动过速机制认识的发展,针对室性心律失常的导管消融越来越凸显其重要性,已经成为根治、防止和减少复发的重要治疗方法。随着心脏电生理和标测技术的发展,尤其是CARTO和EnSite心内非接触式标测技术的发展,发现在室 Ventricular arrhythmia is an important cause of sudden cardiac death. In recent years, with the development of the understanding of ventricular tachycardia mechanism, catheter ablation targeting ventricular arrhythmia has become more and more important, which has become a cure and prevention And reduce the recurrence of the important treatment. With the development of cardiac electrophysiology and mapping technology, especially the development of intracardiac non-contact mapping technology in CARTO and EnSite,
