Donkey Heart Rate and Heart Rate Variability: A Scoping Review

Animals, 2023
Heart rate (HR) and heart rate variability (HRV) are commonly used physiological measures in animals. While several studies exist on horse HRV, less information is available for donkeys.

FUZZY LOGIC APPROACH FOR HEART RATE VARIABILITY

Journal of V. N. Karazin Kharkiv National University: Series Medicine, 2021
Intrioution. The heart rate variability (HRV) is based on measuring (time) intervals between R-peaks (of RR-intervals) of an electrocardiogram (ECG) and plotting a rhythmogram on their basis with its subsequent analysis by various mathematical methods ...

Addition of 24‐Hour Heart Rate Variability Parameters to the Cardiovascular Health Study Stroke Risk Score and Prediction of Incident Stroke: The Cardiovascular Health Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundHeart rate variability (HRV) characterizes cardiac autonomic functioning. The association of HRV with stroke is uncertain. We examined whether 24‐hour HRV added predictive value to the Cardiovascular Health Study clinical stroke risk score (CHS‐

Heart Rate Variability Modulates Interoceptive Accuracy

Frontiers in Neuroscience, 2021
Our emotional experiences depend on our interoceptive ability to perceive and interpret changes in our autonomous nervous system. An inaccurate perception and interpretation of autonomic changes impairs our ability to understand and regulate our ...

Heart-Rate Variability—More than Heart Beats?

Frontiers in Public Health, 2017
Heart-rate variability (HRV) is frequently introduced as mirroring imbalances within the autonomous nerve system. Many investigations are based on the paradigm that increased sympathetic tone is associated with decreased parasympathetic tone and vice ...
