Heart rate variability (HRV) is a predictor of mortality and morbidity after non-lethal cardiac
ischemia, but the relation between preoperatively measured HRV and intra-and …

Purpose The autonomic nervous system interacts with the immune system via the
inflammatory response. Heart rate variability (HRV), a marker of autonomic activity, is …

The Poincaré plot for heart rate variability analysis is a technique considered geometrical
and non-linear, that can be used to assess the dynamics of heart rate variability by a …

A growing trend among clinical studies is the use of heart rate monitors (HRMs) for
assessment of heart rate variability (HRV). These instruments offer a convenient alternative …

Background With prolonged physical activity, it is important to maintain adequate fluid
balance. The impact of consuming isotonic drinks during and after exercise on the …

Decreased heart rate variability (HRV) is related to higher morbidity and mortality. In this
study we evaluated the linear and nonlinear indices of the HRV in stable angina patients …

Objective: To evaluate a possible evolutionary post-heart transplant return of autonomic
function using quantitative and qualitative information from recurrence plots. Methods: Using …

Background: Heart rate variability (HRV) indices may detect autonomic changes with good
diagnostic accuracy. Type diabetes mellitus (DM) individuals may have changes in …

Various studies have indicated that music therapy with relaxant music improves cardiac
function of patients treated with cardiotoxic medication and heavy-metal music acutely …

Objective: Dysfunction of cardiac autonomic nerve system is considered as one of risk
factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used …
