Heart rate variability analysis [PDF]

Acta Physiologica Hungarica, 2001
The expansion of heart rate variability analysis has been facilitated by the remarkable development of computer sciences and digital signal processing during the last thirty years. The beat-to-beat fluctuation of the heart rate originates from the momentary summing of sympathetic and parasympathetic influences on the sinus node.

Interaction between heart rate variability and heart rate in pediatric population.

Frontiers in Physiology, 2015
Background: Heart rate variability (HRV) is primarily heart rate (HR) dependent, and therefore, different HR may exert different impact on HRV. The objectives of the study were to evaluate the effect of HR on HRV in children and to determine whether HRV ...

A pilot study of patch Holter electrocardiograph recordings in healthy cats [PDF]

Open Veterinary Journal, 2022
Background: A patch Holter electrocardiograph (P-Holter) is cordless, making it lightweight unlike the conventional Holter electrocardiograph (C-Holter). A P-Holter can also take continuous measurements. For up to 14 days without replacing the battery or

Heart Rate Variability [PDF]

Hypertension, 2014
See related article, pp 1334–1343 In this issue of Hypertension , Monfredi et al1 address a phenomenon that has been repeatedly described in the literature2–5 but, nevertheless, went largely unnoticed by the scientific community using heart rate variability (HRV) to assess cardiac autonomic control or to predict cardiovascular health.

Determinants of short-period heart rate variability in the general population [PDF]

, 2001
Decreased heart rate variability (HRV) is associated with a worse prognosis in a variety of diseases and disorders. We evaluated the determinants of short-period HRV in a random sample of 149 middle-aged men and 137 women from the general population ...

Artificial intelligence for heart rate variability analyzing with arrhythmias [PDF]

, 2019
Introduction. Existing standards of Heart Rate Variability (HRV) technology limit its use to sinus rhythm. A small number of extrasystoles is allowed, if the device used has special procedures for the detection and replacement of ectopic complexes ...

Heart rate and heart rate variability in infants during olfactory stimulation

Annals of Human Biology, 2019
Background: Various plant odours have been shown to decrease heart rate and increase parasympathetic nervous activity. However, ‘innate’ autonomic responses without the influences of experience, assumptions and prejudices of odours remains unclear.
