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...
Prediction of maximal heart rate percent during constant intensity efforts on trained subjects
Heart Rate Percent Treadmill Exercise Prediction Triangular Test
2013/1/30
The purpose of this study is to evaluate the relationship between %HRmax and %vVO2max at constant efforts made at different intensities. In randomized order, males healthy subjects (Age: 25 ± 7 years,...
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...
Artificial arterial blood pressure artifact models and an evaluation of a robust blood pressure and heart rate estimator
Artificial arterial blood pressure a robust blood pressure heart rate estimator
2010/2/25
The KF/SQI-fusion method described in this article was shown to provide an accurate estimate of blood pressure and HR derived from the ABP waveform even in the presence of high levels of persistent no...
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...
The Effects of Meperidine Analgesia during Labor on Fetal Heart Rate
meperidine labor analgesia fetal heart rate
2009/4/8
To estimate the effects of intramuscular meperidine analgesia on fetal heart rate (FHR) patterns compared with placebo. In a prospective randomized study, 150 healthy women with singleton term pregnan...
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...
Identifying diabetic patients with cardiac autonomic neuropathy by heart rate complexity analysis
diabetic patients cardiac autonomic neuropathy heart rate
2010/2/25
Cardiac autonomic neuropathy (CAN) in diabetes has been called a "silent killer", because so few patients realize that they suffer from it, and yet its effect can be lethal. Early sub clinical detecti...
Heart rate analysis in normal subjects of various age groups
Heart rate analysis normal subjects of various age groups
2010/3/1
In this work, the different linear and nonlinear parameters evaluated show a particular range for various cardiac abnormalities. And the results of these were subjected to 't' test with more than 89% ...
EFFECT OF AQUEOUS LEAF EXTRACT OF TRIDAX PROCUMBENS ON BLOOD PRESSURE AND HEART RATE IN RATS
Tridax procumbens Blood pressure heart rate acetylcholine
2009/12/17
The Cardiovascular effects of aqueous extract from the leaf of Tridax procumbens were investigated on anaesthetized Sprague-Dawley rat. The intravenous administration of 3, 6, and 9mg/Kg of the aqueo...
