Chronic right ventricular (RV) pacing is an often-unrecognized cause of cardiomyopathy, despite research that has revealed that chronic RV pacing can cause significant cardiomyopathy and heart failure, leading causes of hospitalization in the United States. Studies have found that chronic RV apical pacing results in ventricular dyssynchrony, reduced cardiac function, and heart failure. This article describes the deleterious effects of permanent cardiac pacemakers and their association with cardiomyopathy and heart failure. More research is needed to investigate other forms of pacing and treatment to prevent ventricular dyssynchrony and myocardial remodeling.
慢性右心室（RV）起搏是心肌病的一个常被忽视的原因，尽管研究已经表明慢性 RV 起搏会导致严重的心肌病和心力衰竭，这也是美国住院的主要原因。研究发现，慢性 RV 心尖部起搏会导致心室不同步、心功能降低和心力衰竭。本文描述了永久性心脏起搏器的有害影响及其与心肌病和心力衰竭的关系。需要进一步研究其他形式的起搏和治疗方法，以预防心室不同步和心肌重构。
