Abstract：
Ventricular arrhythmias present with a wide spectrum of clinical manifestations, from mildly symptomatic frequent premature ventricular contractions to life-threatening events. Pathophysiologically, idiopathic ventricular arrhythmias occur in the absence of structural heart disease or ion channelopathies. Ventricular arrhythmias in the context of structural heart disease are usually determined by scar-related reentry and are associated with increased mortality. Catheter ablation is safe and highly effective in treating ventricular arrhythmias. The proper characterization of the arrhythmogenic substrate is essential for accurate procedural planning. We provide an overview on the main mechanisms of ventricular arrhythmias and their implications for catheter ablation.
摘要：
室性心律失常具有广泛的临床表现，从轻度症状频发室性早搏到危及生命的事件。病理生理学，特发性室性心律失常发生在没有结构性心脏病或离子通道病的情况下。结构性心脏病中的室性心律失常通常由疤痕相关的折返决定，并与死亡率增加有关。导管消融治疗室性心律失常是安全有效的。致心律失常底物的正确表征对于准确的程序计划至关重要。我们概述了室性心律失常的主要机制及其对导管消融的影响。
