[Reflection of distribution of the epicardial ventricular potential on the dog body surface during electrical stimulation of the myocardium]. / Otobrazhenie na poverkhnosti tulovishcha sobaki raspredeleniia potentsiala na épikarde zheludochkov pri élektricheskoi stimuliatsii miokarda.

Electrical pacing of the apex, base, and free wall of the heart right and left ventricles, as well as the left ventricle's interventricular septum revealed that localisation of the ectopic focus determined the sequence of ventricular depolarisation, the site formation, and the pathway of displacement of the areas' positive and negative potentials and their extrema on the thoracic surface. Time of the mutual movement (inversion) of positive and negative zones on the body surface was found to depend on the pacing site in the wall of ventricles.
