The effects of baseline heart rate recovery normality and exercise training protocol on heart rate recovery in patients with heart failure

The effects of baseline heart rate recovery normality and exercise training protocol on heart rate recovery in patients with heart failure

OBJECTIVE It is unclear which exercise training protocol yields superior heart rate recovery (HRR) improvement in heart failure (HF) patients. Whether baseline HRR normality plays a role in the improvement is unknown. We hypothesized that an exercise training protocol and baseline HRR normality would be factors in altering HRR in HF patients. METHODS In this prospective, randomized, controlle...

Effect of Exercise Training on Heart Rate Variability in Patients with Heart Failure After Percutaneous Coronary Intervention

Background: This study aims to evaluate the effect of exercise training on heart rate variability (HRV) and to determine the correlation between parameters of HRV and the ejection fraction in patients with heart failure after percutaneous coronary intervention.Material and Methods: Fifty patients with left ventricular ejection fraction ≤ 40% undergone percutaneous coronary intervention were r...

Variable effects of physical training of heart rate variability, heart rate recovery, and heart rate turbulence in chronic heart failure.

BACKGROUND Heart rate variability (HRV), heart rate turbulence (HRT), and heart rate recovery (HRR), indices that reflect autonomic nervous system (ANS) activity, are outcome predictors in patients with chronic heart failure (CHF). It is not clear, however, whether they reflect the same components of ANS activity. No study has examined the effects of physical training (PT) training on HRV, HRT,...

Abnormal heart rate recovery in patients with heart failure: an important target for exercise training treatment

Oxygen Kinetics and Heart Rate Response during Early Recovery from Exercise in Patients with Heart Failure

Background. The purpose of this study was to assess the post-exercise O(2) uptake and heart rate response in patients with heart failure (HF) in comparison to healthy individuals. Methods and Results. Exercise testing of all subjects was conducted according to the RITE-protocol. The study subjects were classified according to their peak oxygen uptake (peak VO(2)) in four groups: healthy individ...
