摘要
By the method of multichannel synchronous cardioelectrotopography, sequence of depolarization of intramural atrial layers was studied in representative of ungulate animals-pigs. In the pig atrial myocardium there is revealed a complex picture of spreading of activation fronts, connected with non-uniform anatomical structure and subendocardial (intramural) disposition of area of initial activation. The general character of sequence of depolarization of the pig atrial myocardium is comparable with carnivores (dog) and even-toed (ship) animals.
