目的:本研究比较缺血和非缺血性心肌病患者晚电位的特征和发生率,评估其作为消融靶点的价值。背景:心肌梗死后的疤痕处可经常记录到晚电位。而晚电位是消融靶点有用的指标。目前对非缺血性心肌病患者晚电位的发生率及特征尚未认识清楚。
Objectives: This study compared the characteristics and incidence of late potentials in patients with ischemic and non-ischemic cardiomyopathy to assess their value as targets for ablation. Background: Scar after myocardial infarction can often be recorded to late potentials. While late potentials are useful indicators of ablation targets. At present, the incidence and characteristics of late potentials in patients with non-ischemic cardiomyopathy have not yet been clearly understood.
