目前,由于经导管心内膜和术中心表面或心内膜描绘对致死性室性心律失常(VT)能做到正确定位,以便进行心肌切开,心内膜切除,冷冻凝固术等外科根治疗法。本文应用12导心电图对术中和经导管内膜下描绘定位的17例非缺血性(VT)进行回忆性探讨。结果:在V_1导联上表现rS、QS图形者为左束支阻滞(LBBB)型,V_1表现qR、rR’、rsR’、qR R’时为右束支阻滞(RBBB)型。
Currently, due to the catheterized endocardium and surgical center surface or endocardial mapping of fatal ventricular arrhythmias (VT) can be properly positioned for myocardial incision, endocardial resection, cryo-coagulation and other surgical cure therapy. In this paper, we used the 12-lead electrocardiogram to retrospectively study 17 cases of non-ischemic (VT) intraoperative and endocardial mapping. Results: The images of rS and QS on V 1 lead were LBBB type, and the RBBB type of V 1 was qR, rR ’, rsR’ and qR R ’.
