Abstract

Cardiomyopathies (CMP) are related with scarring tissue due to fibrotic and disarrangement of myocardial fibers that promote an slowed conduction and substrate for sustained reentrant ventricular arrhythmias. Sometimes, CMP can be associated with ventricular extrasystoles but uncommonly originated from scarring tissue. The case report show a patient with nonischemic CMP, frequents premature ventricular contractions and sustained ventricular tachycardia submitted to catheter ablation.

非缺血性心肌病患者致心律失常底物与频繁室性早搏的关系
心肌病(CMP)与心肌纤维纤维化和紊乱导致的瘢痕组织有关,心肌纤维的纤维化和紊乱促进传导减慢和持续折返性室性心律失常的基质。有时,CMP可能与室性早搏有关,但罕见地起源于瘢痕组织。病例报告显示,一名患者患有非缺血性CMP,经常发生室性早搏和持续性室性心动过速,接受导管消融。
