Importance Patients with heart failure with preserved ejection fraction (HFpEF) with a
pacemaker may benefit from a higher, more physiologic backup heart rate than the nominal …

Background In heart failure with preserved ejection fraction (HFpEF), it has been assumed
that pharmacologic heart rate suppression should provide clinical benefits through an …

Background Patients with pacemakers and heart failure with preserved ejection fraction
(HFpEF) or isolated diastolic dysfunction (DD) may benefit from a higher backup heart rate …

Aim Emerging evidence suggests a beneficial effect of higher heart rates in some patients
with heart failure with preserved ejection fraction (HFpEF). This study aimed to evaluate the …

Heart failure with preserved ejection fraction (HFpEF) is increasingly prevalent with a high
socioeconomic burden. Pharmacological heart rate lowering was recommended to improve …

As they noted, the delineation between pneumonia and heart failure (HF) poses a
considerable challenge due to their frequent co-existence in clinical settings. Notably …

Previous research established age-related normal limits for children's heart rates (HRs).
However, children of the same age can have significantly different HRs, depending on …

The physiological parameters of breathing rate and heart rate have been used for vital signs
monitoring of the health status of the human subject for the purpose of wellness. As a result …

-Continuous accelerated physiologic pacing is a promising potential therapy for patients with
HFpEF based on physiologic principles and hemodynamic pacing studies. Further …
