Permanent pacing is a risk factor for the development of heart failure.
No previous study has examined the importance of right ventricular pacing as a risk factor for the development of heart failure (HF) in subjects without a history of HF. A cohort study of patients who underwent initial pacemaker implantation (n = 11,426) was conducted to test the hypothesis that patients with ventricular dyssynchrony created by permanent pacing would develop HF, as shown by new HF hospitalizations or HF-related deaths, at a higher rate than matched controls.
