Clinical Application of Neonatal Instantaneous Heart Rate Monitoring (Part One: Neonatal Instantaneous Heart Rate Response to Apnea)

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...

Application of Optical Heart Rate Monitoring

Since the introduction of portable devices in 1957 by Dr. Norman Holter, heart rate (HR) monitors have been extensively used in clinical practices as a diagnostic and prognostic tool, mainly for cardiovascular diseases. In parallel, the use of HR monitoring devices by sport physiologists to analyze the response of the body to exercise or training stress and to evaluate the training level of ath...

Sound and vibration: effects on infants' heart rate and heart rate variability during neonatal transport.

AIM To measure the effect of sound and whole-body vibration on infants' heart rate and heart rate variability during ground and air ambulance transport. METHODS Sixteen infants were transported by air ambulance with ground ambulance transport to and from the airports. Whole-body vibration and sound levels were recorded and heart parameters were obtained by ECG signal. RESULTS Sound and whol...

Wavelet transform to quantify heart rate variability and to assess its instantaneous changes.

Heart rate variability is a recognized parameter for assessing autonomous nervous system activity. Fourier transform, the most commonly used method to analyze variability, does not offer an easy assessment of its dynamics because of limitations inherent in its stationary hypothesis. Conversely, wavelet transform allows analysis of nonstationary signals. We compared the respective yields of Four...
