Relation of heart rate recovery to heart rate variability in persons with paraplegia
Clinical Autonomic Research, 2010Heart rate recovery (HRR) after treadmill exercise testing is an index of cardiac autonomic activity in non-disabled persons, but it is unknown if this is also the case in individuals with spinal cord injury (SCI). We investigated the relationship between HRR after maximal arm exercise testing and resting autonomic activity in persons with paraplegia.A

The relationship between resting heart rate variability and heart rate recovery
Clinical Autonomic Research, 2009There is limited research available regarding a possible relationship between resting heart rate variability (HRV) and post-exercise heart rate recovery (HRR). The aim of this study was to examine the relationship between resting HRV and HRR after maximal exercise.Sixty-six college age men participated in this study.

Pathophysiological Characteristics of Heart Rate Recovery in Heart Failure
Medicine & Science in Sports & Exercise, 2006Heart failure (HF) is associated with blunted HR recovery after exercise. The determinants of altered HR recovery in HF are unknown. The aim of this study was to investigate clinical correlates of HR recovery in HF patients.Echocardiography, pulmonary function tests, exercise testing, and neurohormonal measurements were performed in 98 HF patients.

Heart rate variability and heart rate recovery in patients with coronary artery ectasia
Coronary Artery Disease, 2010Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries, which is a variant of coronary artery disease (CAD). Increased sympathetic activity or decreased vagal modulation of cardiac function assessed by heart rate variability (HRV) analysis has been associated with an increased risk of coronary artery disease ...

Resting heart rate variability and heart rate recovery after submaximal exercise
Clinical Autonomic Research, 2014Aerobic training accelerates Heart Rate Recovery after exercise in healthy subjects and in patients with coronary disease. As shown by pharmacological autonomic blockade, HRR early after exercise is dependent primarily on parasympathetic reactivation.

Dissociation of heart rate variability and heart rate recovery in well-trained athletes
European Journal of Applied Physiology, 2011The purpose of this investigation was to examine the relationships between aerobic fitness, volume of physical activity (PA), heart rate variability (HRV), and heart rate recovery (HRR) in a group of well-trained endurance athletes. Nineteen endurance athletes participated in this study and had aerobic capacities that placed them above the 99th ...

Abnormal Heart Rate Recovery in Stable Heart Failure Patients
Pacing and Clinical Electrophysiology, 2013BackgroundHeart rate decrease after exercise, that is associated with reactivation of parasympathetic system, is important, as it is also associated with mortality. Previous studies have shown that this is an independent mortality predictor in patients having no coronary artery disease and having normal left ventricular function. In our study, we aimed

Prognostic value of heart rate recovery in patients with heart failure
American Heart Journal, 2006The rate in which heart rate recovers from exercise has recently been shown to be a strong predictor of mortality in patients suspected of having coronary disease, but its prognostic value in patients with heart failure (HF) has not been explored. We sought to assess the prognostic utility of heart rate recovery (HRR) in patients with HF.Eighty-seven ...

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.

Heart rate rises during activity in order to keep up with the higher oxygen requirements of functioning muscles. The autonomic nervous system controls this reaction; sympathetic activation causes an increase in cardiac output and heart rate. The degree of heart rate rise is mostly dependent on the type of exercise, whether it be modest, moderate, or ...
