Abstract
The myocardial reactivity to main regulatory influences (changes of stimulation rate, superfusion of acetylcholine, adrenaline, noradrenaline) was to be higher in right than in left rat atrium. The training-induced increase of some interatrial differences in myocardial reactivity suggests their essential physiological significance.
