Novel heart rate turbulence parameters.
Heart rate turbulence (HRT) is the return of heart rate to equilibrium after a premature ventricular contraction (PVC). It consists of a brief speed up period in heart rate, followed by a slow decrease back to the baseline rate. The concept of HRT was introduced to the medical community by Schmidt et al in 1999. While studying PVC characteristics researchers had noticed that heart rate seemed t...
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,...
متن کاملHeart Rate and Respiratory Rate Influence on Heart Rate Variability Repeatability: Effects of the Correction for the Prevailing Heart Rate
BACKGROUND Since heart rate variability (HRV) is associated with average heart rate (HR) and respiratory rate (RespRate), alterations in these parameters may impose changes in HRV. Hence the repeatability of HRV measurements may be affected by differences in HR and RespRate. The study aimed to evaluate HRV repeatability and its association with changes in HR and RespRate. METHODS Forty health...
متن کاملتغییرپذیری ضربان قلب Heart rate variability))
Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...
