Abstract
The same mediators of the autonomic nervous system can be both triggers and modulators of internal organs activity,
and heart autonomic regulation can be best estimated by studying heart rate variability (HRV). The objective of the present
research is the estimation of both time and spectral HRV parameters in patients with non-rheumatic myocarditis depending
on its clinical course. 58 patients (20 men and 38 women) aged 35,3 1,3 years were examined. 22 (37,9 %) patients
have established acute myocarditis, and 36 (62,1 %) - postmyocardic cardiosclerosis (PMC). HRV parameters were
estimated depending on the disease stage, and on presence of heart rhythm disturbances. Patients with acute myocarditis
compared to those having PMC had decreased HRV parameters (SDNN, SDANN, SDNNi, pNN50, rMSSD) refl ecting
vegetative imbalance, and ventricular ecthopic activity in patients with myocarditis is associated with the activation of
both sympathetic and parasympathetic system, and these changed are more expressed in patients with high ventricular
extrasystole gradation.
