Key result
Constant right ventricular pacing contributes to the development of pacemaker-induced cardiomyopathy, which can present as a phenotype of heart failure with preserved ejection fraction.
Why the study?
What is the role of constant right ventricular pacing in the development of pacemaker-induced cardiomyopathy, particularly with preserved ejection fraction?
What is the role of constant right ventricular pacing in the development of pacemaker-induced cardiomyopathy, particularly with preserved ejection fraction?
Highlights the need to recognize pacemaker-induced cardiomyopathy even in patients with preserved left ventricular ejection fraction.
May prompt HFpEF evaluation for pacing effects; leaves open prospective trials on prevention.
Pacemaker-induced cardiomyopathy (PICM) is a complication of frequent right ventricular pacing, which in most studies is regarded as a decrease in the left ventricular ejection fraction with constant right ventricular pacing. However, cases of PICM with preserved left ventricular ejection fraction are insufficiently described, since the onset most often occurs as a phenotype of heart failure with preserved ejection fraction. The paper analyzes the studies on the role of constant right ventricular pacing and its contribution to PICM development.

Андреев et al. (2025) conducted a review in Pacemaker-induced cardiomyopathy. Right ventricular pacing was evaluated. Constant right ventricular pacing contributes to the development of pacemaker-induced cardiomyopathy, which can present as a phenotype of heart failure with preserved ejection fraction.
