Diaphragmatic breathing, a deep breathing technique, has been reported to improve
autonomic function by reducing sympathetic activity and increasing baroreflex sensitivity …

Background The use of heart rate variability as a tool capable of discriminating individuals
with diabetes mellitus is still little explored, as its use has been limited to comparing those …

Background and Purpose—Prediction of stroke in healthy individuals is challenging and
there is a diurnal variation of stroke onset. We hypothesized that heart rate variability with a …

We investigated the influence of angiotensin-converting enzyme inhibitor (ACEi) treatment
and physical exercise on arterial pressure (AP) and heart rate variability (HRV) in volunteer …

Autonomic cardiac dysfunction is a common complication after acute ischemic stroke (IS).
We recruited 75 patients with acute IS with measurements of autonomic cardiac function …

This study aimed to investigate the effect of acute psychological stress on autonomic
function and arterial stiffness, and to test a mediating role of changes in autonomic function …

Objective: We aimed at evaluating right ventricular remodeling (structure, function, and
mechanics) and heart rate variability (HRV), as well as their interaction, in untreated …

Fundamento A hipertensão arterial sistêmica (HAS) é uma doença multifatorial, altamente
prevalente e associada a riscos à saúde. Objetivo O objetivo deste estudo foi investigar a …

The identification of patients with obstructive sleep apnea (OSA) is important because of
morbidities associated with OSA. A previous adult study demonstrated the use of heart rate …

Abnormalities of the autonomic nervous system have been repeatedly shown in
hypertension. We studied the associations between being overweight, blood pressure …
