Heart 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 کاملTest-retest reproducibility of heart rate recovery after treadmill exercise.
BACKGROUND Slowed heart rate recovery (HRR) of less than 12 beats per minute in the first minute after an exercise stress test has been suggested as a useful addition to the criteria currently used to assess exercise stress test results. Although HRR has been tested in large populations, the short-term test-retest stability (reproducibility) of abnormal HRR for an individual has not been assess...
متن کاملHeart Rate Recovery as a Novel Test for Predicting Cardiac Involvement in Beta-Thalassemia Major.
BACKGROUND Abnormal heart rate recovery (HRR) is predictive of cardiac mortality. Autonomic abnormalities in beta-thalassemia major (TM) patients have been reported in previous studies. However, the importance of low HRR in exercise stress test in TM patients has not yet been ascertained. Therefore, this study will be the first of its kind in the literature. METHODS Exercise stress test was p...
متن کاملRelative Risk Forests for Exercise Heart Rate Recovery as a Predictor of Mortality
Recent studies have confirmed heart rate fall after treadmill exercise testing, or heart rate recovery, as a powerful predictor of mortality from heart disease. Heart rate recovery depends on central reactivation of vagal tone and decreased vagal activity is a risk factor for death. If heart rate recovery is defined as the fall in heart rate after 1 minute following peak exercise, then a heart ...
متن کاملHEART RATE AS A RISK FACTOR In CARDIAC DISEASE
There is a lot of evidence that elevated heart rate is an independent risk factor for mortality and morbidity in healthy individuals with and without hypertension and in patients with coronary artery disease (CAD), acute myocardial infarction (AMI), and heart failure. Several large placebo-controlled trials of patients with AMI or heart failure have demonstrated that beta-blockers reduce mortal...
