Low Heart Rate Variability in Healthy Young Adult MalesMillis, Richard MCarlyle, Stanley PHatcher, Mark DBond, Vernon
Background: The aim of this study was the evaluation of heart rate variability (HRV) time and frequency domain indices and their correlation with age, gender, mean heart rate and mean RR interval. Material and methods: We examined 372 healthy subjects aged from 4 to 18 years (mean age 11...
A potential role for resting HRV underlying the physiology and prediction of higher risk heart rate (HR) responses to graded exercise testing was then explored. The consequent chapter found that resting vagally mediated HRV measures were able to predict a low risk but not a high risk HR ...

Impact of sex and gonadal steroids on prolongation of ventricular repolarization and arrhythmias induced by I(K)-blocking drugs. BACKGROUND: Mechanisms for longer rate-corrected QT intervals and higher incidences of drug-induced torsade de pointes in women than in men are incompletel......
Your resting heart rate, however, should not change significantly with normal aging. What is a Dangerous Heart Rate? There are two types of dangerous heart rates: Too high – Called tachycardia, it’s a heart rate consistently above 100 beats per minute. Too low – Called bradycardia, it’...
Level of agreement was excellent with a mean difference of 1% in the very low frequency and low-frequency band and 14% in the high-frequency band. Reliability of both HRV and PRV was moderate to high. CONCLUSION: Our data show that PRV derived from non-invasive blood pressure waveforms ...
The relatively low metabolic rate of the fetus combined with thermoregulation provided by the mother leads to an important reduction in fetal oxygen consumption relative to the newborn infant.11 Another important factor contributing to adequate fetal oxygenation is the sustained increase in fetal ...
