室性早搏和非持续性室速的心电图表现、定位及消融

The ECG manifestation,location and ablation of premature ventricular contraction and nonpersistent ventricular tachycardia

室性早搏(室早)是临床上最常见的心律失常之一。室早的射频消融治疗十分有效,并发症的发生率低于1%,但对适应证未达成共识。消融成功率与室早的起源部位高度相关。不论是术前还是术中,标准12导联心电图均有助于精准定位早搏起源,从而选定治疗策略和操作入路。

Premature ventricular contraction(PVC)is one of the most commonly seen arrhythmias in clinical practice.Radiofrequency ablation of PVC proves to be very effective and the incidence of complications is lower than 1%.However,it is still controversial about its indicatio.The success rate of ablation and the origin site of PVC is highly correlated.Whether preoperatively or intraoperatively,standard 12-lead ECG both helps to accurately locate the origin site of PVC,and thus contributes to determine the treatment strategies and operation path.
