Test-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 immediately after exercise as a predictor of mortality.
BACKGROUND The increase in heart rate that accompanies exercise is due in part to a reduction in vagal tone. Recovery of the heart rate immediately after exercise is a function of vagal reactivation. Because a generalized decrease in vagal activity is known to be a risk factor for death, we hypothesized that a delayed fall in the heart rate after exercise might be an important prognostic marker...
متن کاملHeart rate recovery after exercise: a predictor of ventricular fibrillation susceptibility after myocardial infarction.
Heart rate recovery after exercise, thought to be related to cardiac parasympathetic tone, has been shown to be a prognostic tool for all-cause mortality. However, the relationship between this variable and confirmed susceptibility to ventricular fibrillation (VF) has not been established. Therefore, myocardial ischemia was induced with a 2-min occlusion of the left circumflex artery during the...
متن کاملHeart rate recovery after exercise is a predictor of mortality, independent of the angiographic severity of coronary disease.
OBJECTIVES We sought to determine whether abnormal heart rate recovery predicts mortality independent of the angiographic severity of coronary disease. BACKGROUND An attenuated decrease in heart rate after exercise, or heart rate recovery (HRR), has been shown to predict mortality. There are few data on its prognostic significance once the angiographic severity of coronary artery disease (CAD...
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 ...
