引言频繁的室性早搏（PVC）可引起心肌病（CM）。期外收缩后增强（PESP）和不规则性被认为是PVC-CM的触发因素。由于这两种现象也可以在房性期前收缩（PAC）中发现，因此推测频繁的PAC具有类似的后果。方法和结果一项单中心、回顾性研究纳入了所有接受14天霍尔特监测的连续患者（2014年11月至2016年10月）。根据异位负荷将患者分为4组，第1组（
Introduction Frequent premature ventricular contractions (PVCs) can cause cardiomyopathy (CM). Postextrasystolic potentiation (PESP) and irregularity have been in implicated as triggers of PVC-CM. Because both phenomena can also be found in premature atrial contractions (PACs), it is speculated that frequent PACs have similar consequences. Methods and results A single-center, retrospective study included all consecutive patients undergoing a 14-day Holter monitors (November 2014 to October 2016). Patients were divided into four groups by ectopy burden group 1 (
