Variable 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 Turbulence: A Review
Heart rate turbulence (HRT) is a recently coined phrase that describes the short term fluctuation in sinus cycle length that follows a ventricular premature complex (VPC). Its proven clinical significance lies in its ability to predict mortality and sudden cardiac death following myocardial infarction, although small studies suggest that it is also applicable to many other cardiac diseases. Thi...
متن کاملHeart Rate Turbulence Analysis in Subclinical Hypothroidism Heart Rate Turbulence in Hypothyroidism.
BACKGROUND Heart rate turbulence (HRT) is a baroreflex-mediated biphasic reaction of heart rate in response to premature ventricular beats. Abnormal HRT identifies patients with autonomic dysfunction or impaired baroreflex sensitivity. The aim of the present study was to demonstrate the effect of subclinical hypothyroidism (SCH) on cardiac autonomic function using HRT parameters. METHODS The ...
متن کاملNovel 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 کاملHeart rate turbulence in patients with chronic heart failure.
BACKGROUND Heart rate turbulence (HRT) has been shown to predict the prognosis after myocardial infarction (MI), but its prognostic value in patients with chronic heart failure (CHF) has not yet been well established. AIM To evaluate HRT in patients with CHF and assess the prognostic significance of HRT in this group. METHODS The study group consisted of 82 patients with CHF and left ventri...
