Key result
Increasing pacemaker heart rate to 70 bpm is linked to reduced pulse pressure in elderly patients.
Why the study?
Low DBP and high PP are linked to higher stroke risk and cognitive impairment, and raising resting HR could lower PP and improve cerebral perfusion in pacemaker patients.
Does increasing resting heart rate via pacemaker programming reduce pulse pressure in elderly patients with dual-chamber permanent pacemakers?

Does increasing resting heart rate via pacemaker programming reduce pulse pressure in elderly patients with dual-chamber permanent pacemakers?
Increasing resting heart rate to 70 bpm in elderly patients with dual-chamber pacemakers may reduce pulse pressure, offering a potential programming strategy to improve hemodynamics in those with poor vascular compliance.

May support testing 70 bpm resting rates to lower pulse pressure in elderly pacemaker patients; leaves open whether this improves outcomes.
Background: Low diastolic blood pressure (DBP) and high pulse pressure (PP), markers of vascular stiffness, are linked to higher stroke risk and cognitive impairment. Increasing resting heart rate (HR) in pacemaker patients could lower PP and enhance cerebral perfusion. This study examines how raising resting HR affects PP in patients with higher vascular risk. Methods: A cross-sectional interventional study involved 21 patients (mean age, 77 years; 9 male, 12 female) over age 65 years with dual-chamber permanent pacemakers and normal ventricular function. Hemodynamic parameters were measured at 5-minute intervals at baseline and every 10 beats per minute (bpm) up to 100 bpm using the Finapres NOVA plethysmograph. The effects of higher pacing rates on PP, systolic BP, DBP, and cardiac output were analyzed. All patients remained asymptomatic, and no adverse events were observed during the study. The findings indicated variability in response, with most patients showing decreased PP at higher HRs. Conclusions: An increased HR to 70 bpm reduced PP in most patients with dual-chamber permanent pacemakers and sinus rhythm, suggesting a way to improve hemodynamics in patients with poor vascular compliance. Customized HR settings may optimize PP and reduce the risk of cognitive decline or stroke. Further research is needed to evaluate for risks of pacemaker-induced cardiomyopathy in individuals requiring frequent ventricular pacing.

Mian et al. (2025) conducted a cross-sectional in dual-chamber permanent pacemakers and normal ventricular function (n=21). Increasing resting heart rate via pacemaker vs. baseline was evaluated on pulse pressure, systolic BP, diastolic BP, and cardiac output (p== 0.25). Increasing pacemaker heart rate to 70 bpm reduced pulse pressure in most elderly patients with dual-chamber permanent pacemakers and sinus rhythm.
