Heart Rate Dynamics in Patients with Obstructive Sleep Apnea: Heart Rate Variability and Entropy

Entropy, 2019
Background: Obstructive sleep apnea (OSA), a highly prevalent sleep disorder, is closely related to cardiovascular disease (CVD). Our previous work demonstrated that Shannon entropy of the degree distribution (EDD), obtained from the network domain of ...

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.

Heart rate and heart rate variability in horses undergoing hot and cold shoeing.

PLoS ONE
Heart rate variability (HRV) is a frequently used indicator of autonomic responses to various stimuli in horses. This study aimed to investigate HRV variables in horses undergoing cold (n = 25) or hot (n = 26) shoeing.

The Relationship Between Heart Rate Recovery and Heart Rate Variability in Coronary Artery Disease

Annals of Noninvasive Electrocardiology, 2006
Background: Reduced heart rate recovery (HRR) in coronary artery disease (CAD) is predictive of increased cardiovascular mortality and is related to reduced parasympathetic tonus. Objective: To investigate HRR and heart rate variability (HRV) measured at

Heart rate variability while assessing transplanted heart reinnervation

Инновационная медицина Кубани, 2019
Key difference of the transplanted heart is its full surgical denervation which causes features of transplanted heart physiology. Eventually a great number of studies appeared and they showed signs of innervation partial restoration and its influence on ...

Heart Rate Variability, Deceleration Capacity of Heart Rate, and Death: A Veteran Twins Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Autonomic function can be measured noninvasively using heart rate variability (HRV), which indexes overall sympathovagal balance. Deceleration capacity (DC) of heart rate is a more specific metric of vagal modulation.

Weaning reduces body temperature and heart rate, and increases heart rate variability in ewes

Smart Agricultural Technology
Weaning elicits strong responses in ewes and lambs, which makes it a significant welfare concern; however, limited and sometimes contradictory information is available on the physiological responses of dams at weaning.

Investigating asymmetry in fetal and maternal heart rate accelerations and decelerations

Scientific Reports
This study investigates the asymmetry in heart rate (HRA) during fetal development in the fetus and mother. R-R intervals from noninvasive fetal and maternal ECG signals from 102 pregnant women whose gestational age ranges from 20 to 40 weeks were ...
