Clinical application of neonatal instantaneous heart rate monitoring (Part one: neonatal instantaneous heart rate response to apnea).

Introduction; Fetal monitoring of instantaneous heart rate (IHR) is one of major advances in recent perinatal medicine. It is widely accepted that changing pattern of fetal IHR associated with uterine contraction will reflect fetal well or ill being. Uterine contraction produces temporary hypoxia to the fetus and apnea does the same to the neorlate. Therefore we analysed changing patterns of ne...

[Circadian profiles of heart rate and its instantaneous variability in patients with chronic Chagas' disease].

INTRODUCTION AND OBJECTIVES Impairment of the autonomous nervous system in early stages of Chagas' disease is still a matter of debate, although multiple approaches (including heart rate response to orthostatism and the Valsalva maneuver, and spontaneous variability) have been used to ascertain its occurrence. The circadian profile of heart rate and its variability have not been investigated in...

Performance Comparison of Time-Frequency Distributions for Estimation of Instantaneous Frequency of Heart Rate Variability Signals

The instantaneous frequency (IF) of a non-stationary signal is usually estimated from a time-frequency distribution (TFD). The IF of heart rate variability (HRV) is an important parameter because the power in a frequency band around the IF can be used for the interpretation and analysis of the respiratory rate but also for a more accurate analysis of heart rate (HR) signals. In this study, we c...

Analysis 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...

تغییرپذیری 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...
