Resting heart rate and heart rate reserve in advanced heart failure have distinct pathophysiologic correlates and prognostic impact: a prospective pilot study.
OBJECTIVES The purpose of this study was to compare the prognostic impact of clinical and biomarker correlates of resting heart rate (HR) and chronotropic incompetence in heart failure (HF) patients. BACKGROUND The mechanisms and underlying pathophysiological influences of HR abnormalities in HF are incompletely understood. METHODS In a prospective pilot study, 81 patients with advanced sys...
متن کاملAssociations Between Resting Heart Rate and Antisocial Behavior
Studies testing the relationship between autonomic nervous system function as indexed by low resting heart rate and antisocial behavior have found that low resting heart rate is positively correlated with a wide range of antisocial behavior measures. The aim of this review was to assess the influence of heart rate (HR) level and HR variability (HRV) on the relationship between behavioral variab...
متن کاملHeart rate variability and heart rate recovery as prognostic factors
BACKGROUND AND AIM Heart rate (HR) can appear static and regular at rest, during exercise or recovery after exercise. However, HR is constantly adjusted due to factors such as breathing, blood pressure control, thermoregulation and the renin-angiotensin system, leading to a more dynamic response that can be quantified using HRV (heart rate variability). HRV is defined as the deviation in time b...
متن کاملPrognostic significance of PVCs and resting heart rate.
BACKGROUND We sought to evaluate the prognostic significance of premature ventricular contractions (PVCs) on a routine electrocardiogram (ECG) and to evaluate the relationship between heart rate and PVCs. METHODS Computerized 12-lead ECGs of 45,402 veterans were analyzed. Vital status was available through the California Health Department Service. RESULTS There were 1731 patients with PVCs ...
متن کاملVariable 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,...
