Review of the Impact of Physical Exercise on Heart Rate Variability in Hypertensive Patients
Abstract
The heart is controlled by the autonomic nervous system (ANS), oscillating between sympathetic and parasympathetic predominance according to exogenous and endogenous stimuli. ANS activity can be assessed indirectly by heart rate variability (HRV). This review aimed to assess the impact of physical exercises on HRV in hypertensive patients. A literature review was performed, searching the PubMed, SciELO, LILACS and Google Scholar databases. 10 clinical trials, published in the last 5 years, were included. It is concluded that physical exercise has a positive influence on HRV, altering the morbidity and mortality of systemic arterial hypertension, but that at the same time there was no significant difference when comparing hypertensive and normotensive individuals.
