title: [The process of heart ventricle depolarization and the formation of an electrocardiographic QRS complex in the frog].
abstract: Using intramural multipolar electrode technique, the pattern of propagation of the heart ventricle depolarization was studied in the frog Rana temporaria. The depolarization wave from the middle part of subendocardial layers was shown to spread to the apex and base of the heart and, simultaneously, to the epicardium. The ECG complexes are formed by the electrical activity of the endocardial, intramural and epicardial layers.
