The exercise training restores the heart rate variability in heart failure patients. A systematic review [El entrenamiento físico restaura la variabilidad del ritmo cardiaco en la insuficiencia cardiaca. Revisión sistemática]
(Instituto Nacional de Cardiologia Ignazio Chavez, 2017)
Heart rate dynamics during a treadmill cardiopulmonary exercise test in optimized beta-blocked heart failure patients
(Faculdade de Medicina / USP, 2008)
BACKGROUND: Calculating the maximum heart rate for age is one method to characterize the maximum effort of an individual. Although this method is commonly used, little is known about heart rate dynamics in optimized ...
Exercise heart rates in patients with hypertrophic cardiomyopathy
(Elsevier, 2015)
The exercise heart rate (HR) profile and its relation to cardiac function and arrhythmias were investigated in patients with hypertrophic cardiomyopathy (HC). Chronotropic response (CR) and heart rate recovery (HRR) were ...
Heart-rate variability in low-risk prematurely born infants reaching normal term: A comparison with full-term newborns
(1993)
To investigate the influence of prematurity and postnatal age on the maturation of the autonomic nervous system function, we analysed heart-rate and heart-rate variability in twelve prematurely born infants (<37 weeks ...
