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...
Variability of Serum Concentration of Calcium, Phosphate and Parathyroid Hormone Depending on Time of Blood Draw for Patients on Nocturnal Home Hemodialysis
Nocturnal Hemodialysis Calcium Phosphate Parathyroid Hormone
2013/1/31
Background: Guidelines for patients treated with conventional hemodialysis patients have been written for target serum levels for calcium (Ca), phosphate (PO4) and intact parathyroid hormone (iPTH). N...
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...
Estimation of Respiration Variability by Heart Rate Time Series
Respiratory sinus arrhythmia (RSA) heart rate variability wavelet transform
2009/6/9
The heart rate time series contains two main rhythms : RSA (respiratory sinus arrhythmia), which is synchronous with the respiration rate, and the Mayer wave, which is generally centered around 0.1 Hz...
Interaction between resting pulmonary ventilation function and cardiac autonomic function assessed by heart rate variability in young adults
resting pulmonary ventilation function cardiac autonomic function heart rate variability young adults
2009/3/2
An association between ambient air pollution and reduced cardiac autonomic function assessed by heart rate variability (HRV) mainly in elderly persons has been suggested by a number of epidemiologic...
Inward-attention meditation increases parasympathetic activity：a study based on heart rate variability
Inward-attention meditation parasympathetic activity heart rate variability
2009/3/2
Phenomenon of the heart rate variability (HRV) during various meditation techniques has been reported. However, most of these techniques emphasized the skill of slow breathing (< 0.15 Hz). This pape...
Assessment of pulse rate variability by the method of pulse frequency demodulation
pulse rate variability pulse frequency demodulation
2010/2/26
The PFDM of pulse wave signal provides a reliable assessment of PRV. Given the popularity of pulse wave equipments, PFDM may open new ways to the studies of long-term assessment of cardiovascular vari...
