中文摘要：

起源于冠状静脉系统的室性心律失常并不少见,但是,该部位的解剖及毗邻结构复杂,导管消融困难,成功率较低。本文拟对冠状静脉系统的解剖及毗邻结构、心电图特征及导管消融进行综述,旨在提高该部位起源的室性心律失常导管消融成功率。

英文摘要：

Ventricular arrhythmia originating from the coronary venous system （CVS） is not rare in clinical practice. However, the success rate of catheter ablation is low due to the complicated anatomical structure of CVS and its adjacent tissue. This paper reviews on the anatomical structure of CVS and its adjacent tissue, and the ECG features and catheter ablation of ventricular arrhythmia, aiming to elevate the success rate of catheter ablation of ventricular arrhythmia originating from this site.
