Heart rate variability analysis (HRV) under the influence of atropine and propranolol

Abstract

Sensitiveness and reactivity of the autonomous nervous system, its sympathetic and parasympathetic parts, can serve as diagnostic and prognostic criteria under the testing factor. It is the functional loading caused by introduction of the blocker of the cardiac rhythm autonomous control that allows testing the correspondent link of the physiology function control system. We have chosen the introduction of atropine and propranolol in different doses as a functional loading during the HRV research. The use of the blockers was accompanied by the opposite changes of such statistical parameters, as SDNN, RMSSD, CV. The character of spectral fluctuations also in a contrary manner changed in response to the introduction of blockers.
