Heart rate variability and fatty acid content of blood cell membranes: a dose-response study with n−3 fatty acids
sudden cardiac death cardiac arrest ventricular arrhythmias
2016/6/1
Dietary intake of long-chain n23 polyunsaturated
fatty acids (PUFA) may protect against sudden cardiac
death, an event that may be predicted by measurement of heart
rate variability (HRV).
Ultra-Short-Term Heart Rate Variability is Sensitive to Training Effects in Team Sports Players
Court sports athletic monitoring cardiac autonomic system futsal
2016/1/9
The aim of this study was to test the possibility of the ultra-short-term lnRMSSD (measured in 1-min post-1-min stabilization period) to detect training induced adaptations in futsal players. Twenty-f...
Non-Linear Heart Rate Variability and Risk Stratification in Cardiovascular Disease
heart rate variability risk stratification non linear post myocardial infarction congestive heart failure
2015/7/31
Traditional time and frequency domain heart rate variability (HRV) have cardiac patients at risk of mortality post-myocardial infarction. More recently, non linear HRV has been applied to risk stratif...
MENTAL STATUS AND HEART RATE VARIABILITY
heart rate variability mental status psychology POMS factor analysis
2015/7/29
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 y...

Frequency Structure of Heart Rate Variability
heart rate variability structure spectral analysis
2015/7/28
The results let us suppose that there are at least four periodical phenomena of HRV. Two of them have not been discovered and physiologically explained yet. It has also been confirmed that heart rate ...
Exercise Training Improves Heart Rate Variability after Methamphetamine Dependency
HRV SUBSTANCE,USE AUTONOMIC,NERVOUS,SYSTEM PARASYMPATHETIC,ACTIVITY
2017/5/23
Heart rate variability (HRV) reflects a healthy autonomic nervous system and is increased with physical training. Methamphetamine dependence (MD) causes autonomic dysfunction and diminished HRV. We co...
Heart Rate Variability Predicts Emotional Flexibility in Response to Positive Stimuli
Heart Rate Variability Emotional Flexibility Psychological Ratings
2013/2/20
Flexible adaptation to constantly changing environments is linked to mental health and psychological functioning. Heart rate variability (HRV), an index of autonomic flexibility, has been implicated i...
Atrial fibrillation detection by heart rate variability in Poincare plot
Atrial fibrillation detection heart rate Poincare plot
2010/2/25
We analyzed heart beat variability from inter-beat intervals obtained by a wavelet-based detector. We made a Poincare plot using the inter-beat intervals. By analyzing the plot, we extracted three fea...
Fractal Scaling of Heart Rate Variability in Young Habitual Smokers
Heart rate fractal scaling smoking postural change
2009/6/29
The effect of cigarette smoking on the fractal organisation of the heartbeat regulating system was investigated by power spectral analysis. The heart rate variability (HRV) signal was obtained from th...
CARDIO-VASCULAR REACTION AFTER EXERCISE TEST AND SELECTED PARAMETERS OF HEART RATE VARIABILITY
cardio-vascular reaction exercise test heart rate variability
2009/4/2
The aim of our investigation was to check up the dependence between a type of cardiovascular reaction after exercise test and some selected parameters of heart rate variability (HRV) analysed during...
Monitoring of the autonomic nervous system activity during post-marathon recovery by spectral analysis of heart rate variability: a case study
heart rate variability exercise marathon recovery
2009/4/2
Introduction: Vigorous physical exertion, such as a marathon, evokes long lasting changes in the autonomic cardiac regulation and peripheral fatigue.Aim of the study: We investigated changes in the ...
