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 ...

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‐

MENTAL STATUS AND HEART RATE VARIABILITY [PDF]
, 2008 The results let us suppose that there are at least three periodical phenomena of HRV in frequency range related with mental status. Two of them have not been discovered and physiologically explained yet.

An Overview of Heart Rate Variability Metrics and Norms
Frontiers in Public Health, 2017 Healthy biological systems exhibit complex patterns of variability that can be described by mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals between consecutive heartbeats called interbeat intervals (IBIs).
