Maternal Cardiac Autonomic Function and Fetal Behaviour in Hypertensive and Obese Pregnancies
Hypertension in pregnancy is associated with autonomic dysregulation whereas the effects of obesity in pregnancy on maternal cardiac autonomic function are poorly understood. Furthermore, hypertension in pregnancy is associated with placental insufficiency and fetal growth restriction, whereas …

The association of physical activity with prediabetes/type 2 diabetes and cardiac autonomic function
… with prediabetes/type 2 diabetes (pre/T2D) and cardiac autonomic function. The purpose of study 1 was to examine whether using both objectively (accelerometer) and subjectively (questionnaire) measured moderate- to vigorous-intensity physical activity (MVPA) and sedentary time (SED) improves the …

Effects of low-intensity exercise on blood pressure, heart rate, rate-pressure-product and cardiac autonomic function in hypertensive women
… heart rate (HR), rate-pressure-product (RPP) and cardiac autonomic function were examined in menopausal and post menopausal women with hypertension. Eligible participants (n=50) were counterbalanced to either the exercise group or the control group. Using a pretest-posttest design, participants …

Donepezil’s Effect on Cardiac Function in Patients with Alzheimer’s Disease through an In Vivo, Non Invasive Measure of Cardiac Autonomic Function
… of the medication Donepezil (Aricept®) on cardiac autonomic function for individuals diagnosed with mild to moderate (probable) Alzheimer’s disease (AD). Using age (± 3 years) and gender matched controls, differences in heart rate variability (HRV) among individuals with Alzheimer’s disease …

The effects of magnesium administration on cardiac ventricular function, heart rate variability, and myocardial morphological changes in a chronic diabetes disease model in rats
… complications include coronary heart disease, cardiac autonomic neuropathy and ventricular dysfunction. Furthermore, DM is associated with electrolyte disturbances such as those involving potassium, calcium and magnesium (Mg2+). Among these electrolyte disturbances hypomagnesemia is common in …

Cardiac Autonomic Assessment and Diastolic Function in Individuals with Spinal Cord Injury
… the QT-variability index (QTVI) as a measure of cardiac autonomic function in individuals with spinal cord injury (SCI). The secondary purpose was to investigate the influence of cardiac autonomic activity and blood volume on diastolic function in individuals with SCI. Results from Study 1 showed …

Overexpression of human Cu/Zn Superoxide Dismutase in Mice; The Effect of Increase Superoxide Scavenging on Autonomic Control of the Heart.
Dysregulation of the autonomic cardiovascular control is a complication of diseases including diabetes, hypertension, sleep apnea, and aging. A common factor in these conditions is an increase in reactive oxygen species (ROS) in neural, cardiac, and endothelial tissues. Cu/Zn superoxide dismutase …

The effects of magnesium treatment on short-term changes in heart rate variability, ventricular function and lipid profile in streptozotocin-induced diabetic rats
… cardiovascular complications including cardiac autonomic neuropathy, ventricular dysfunction and dyslipidaemia, which are dependent on the duration and severity of the diabetes. Most complications are identified at a late, irreversible stage following long-standing diabetes; therefore, …

The Reproducibility of Short verses Long-Duration Heart Rate Variability Methods and Relations to Aerobic Fitness in Normal Adults
… rate variability (HRV) has been used to evaluate cardiac autonomic function by measuring variations in electrocardiographic R-R intervals between cardiac cycles. HRV was first used to associate decreases in autonomic nervous system (ANS) control with an increased risk of mortality in coronary …

Effect of Postmenopausal Hormone Replacement Therapy on Heart Rate Variability
… variability (HRV), a measure of cardiovascular autonomic balance and a predictor of cardiac morbidity/mortality. Using an exploratory, pre-test/post-test design to describe HRV in postmenopausal women (PMW) before/after six weeks of HRT, twenty-four Black (n=15) and White (n=9) women, (mean …
