ANALYSIS OF CHANGES IN ECG SEGMENT LENGTH BEFORE AND
AFTER PHYSICAL ACTIVITY IN HEIFERS WITH DIFFERENT INITIAL
VEGETATIVE TONUS
A.S. Emel’yanova
In 1,5-2,0-months heifers of the Black-and-White breed the author studied electrophysiological parameters (P–Q, S–T и T–P segments length), initial vegetative tonus, and vegetative reactivity in dynamics for the purpose of estimation of functional prepares state of myocardium to increased workload at the lactation period.
Key words: cardio-vascular activity, variability of cardiac rhythm, vegetative tone, functional reserves, index of control process adequacy.
