The left ventricular summit is a common site of origin of idiopathic ventricular arrhythmias. These arrhythmias are most commonly ablated within the coronary venous system or from other adjacent structures, such as the right ventricular and left ventricular outflow tract or coronary cusp region. When ablation from adjacent structures fails, a percutaneous epicardial approach can be considered, but is rarely successful in eliminating the arrhythmias due to proximity to major coronary vessels and/or epicardial fat.
左心室峰是特发性室性心律失常的常见起源部位。这些心律失常最常于冠状静脉系统内或从其他相邻结构（如右心室和左心室流出道或冠状动脉窦区域）进行消融。当从相邻结构进行消融失败时，可考虑经皮心外膜途径，但由于靠近主要冠状动脉和/或心外膜脂肪，很少能成功消除心律失常。
