Description
Summary:To the Editor: Leadless pacemakers can be implanted safely at the right ventricular apex and have been shown to function well during short-term follow-up studies. 1 , 2 However, the population for whom this pacing mode is appropriate remains to be determined. Patients in the study by Reynolds et al. (Feb. 11 issue) 2 were elderly (mean age, 76 years), and most had hypertension, atrial fibrillation, or both — three known risk factors for future heart failure with or without preserved ejection fraction. Furthermore, a substantial minority of the patients had congestive heart failure (17.0%) or left bundle-branch block (13.5%) at implantation. The . . .
