Heart 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 کاملAnalysis of the Heart Rate Variability before and after Asphyxia
Over the last two decades there has been a widespread interest in the study of variations in the beat-to-beat timing of the heart, known as heart rate variability (HRV). The studies of heart rate variability have allowed access to useful information about disturbances in autonomic regulation, which are a promising marker to quantify autonomic activity. Heart rate variability has become the conv...
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 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...
