室性心律失常包括室性早搏(室早)、非持续性室性心动过速(室速)、持续性室速、心室扑动、心室颤动(室颤)等。恶性室性心律失常主要指发作时伴明显血流动力学障碍,甚至可导致猝死危险的室性心律失常,常见于室速和室颤。本文重点介绍经射频导管消融治疗室速和室颤研究进展。1经射 Ventricular arrhythmia, including premature ventricular contractions (ventricular premature beats), non-sustained ventricular tachycardia (VT), sustained ventricular tachycardia, ventricular flutter, ventricular fibrillation (VF) and so on. Malignant ventricular arrhythmias mainly refers to attack with significant hemodynamic disorders, and even lead to the risk of sudden ventricular arrhythmias, common in ventricular tachycardia and ventricular fibrillation. This article focuses on the progress of radiofrequency catheter ablation in the treatment of ventricular tachycardia and ventricular fibrillation. 1 shot
