特发性室性早搏与室性心动过速起源的心电图判别

Differentiation of the origin of idiopathic premature ventricular contraction and ventricular tachycardia by electrocardiographic characteristics

特发性室性早搏与室性心动过速的有效治疗手段是射频消融,体表12导联心电图对于术前特发性室性早搏与室性心动过速起源的定位有重要指导作用。通过典型的心电图特征来明确特发性室性心律失常的起源,有助于缩短手术时间和提高手术安全性。本文就不同起源的特发性室性早搏与室性心动过速的12导联心电图特征的研究现状和进展作一综述。

Radiofrequency catheter ablation（ RFCA） is an effective therapy for idiopathic premature ventricular contraction（ PVC） and idiopathic ventricular tachycardia（ IVT）. The 12-lead surface electrocardiogram（ ECG） plays an important guide role in locating the origins of idiopathic PVC and IVT before performing RFCA. Differentiating the origins of idiopathic ventricular arrhythmias by typical ECG characteristics helps to shorten the operation time and improve the operation safety. This paper reviews on the current status and progress of the 12-lead ECG features of idiopathic PVC and IVT with different origins.
