ATRIAL fibrillationThe autonomic nervous system (ANS) plays an important role in the initiation and maintenance of atrial fibrillation (AF). However, the meaning of higher heart rate variability (HRV) in predicting AF remains unclear. Among 2100 patients in the Holter registry, a total of 782 ...
The Oura Ring performed near-perfect for resting heart rate (r² = 0.996) and extremely high for heart rate variability (r² = 0.980) when compared to a medical-grade ECG device. READ MORE: How Accurate Are Oura’s Heart Rate & HRV Measurements? What Causes a High Heart Rate? The ...
Higher intracranial pressure variability (ICPV) has been associated with a more favorable cerebral energy metabolism, lower rate of delayed ischemic neurol

These two cortical regions have the highest density in α4β2 nicotinic acetylcholine receptors (nAChRs) within the whole cortex.The aim of the study was to test the association between nAChRs density/availability in the salience network and the heart rate variability in humans. We selected ...
How deceleration capacity (DC) and acceleration capacity (AC) of heart rate associated with atrial fibrillation (AF) and ablation is still not clear. The dynamic changes of AC, DC and conventional heart rate variability (HRV) parameters were characterized in 154 subjects before circumferential pulmon...
Alterations of Autonomic Modulation of Heart Rate Variability in Eating Disorders This cardiac sympathovagal imbalance may be the pathophysiological basis for the higher risk of sudden cardiac death observed in eating disorders. The pathological modifications of HRV and cardiac autonomic modulation might be...
On the single gene level, there was a modest but still statistically significant (P< 0.05; Fisher’s exact test) overlap between the DEGs of laboratory rats and those of giant mole-rats in blood, heart, and skin tissues (Fig. 1a;Tables S25-S29). Common DEGs in the blood of laboratory...
Using 24-hour heart monitors and other tests, the researchers documented increases inheart rate(the number of times a heart beats per minute), reduced heart rate variability (a measure of the heart's rhythmic regularity) and increases in clinical depression and anxiety. ...
Effects of indoor air purification intervention on blood pressure, bloodoxygen saturation, and heart rate variability: A double-blinded cross-over randomiz... The use of indoor air purifier (IAP) has received growing attention as a mitigation strategy for reducing indoor air pollution, but the evi...
