Aim of the study was to verify the topography of intrinsic neural pathways and investigate influence to the electrophysiological parameters and neural control of the heart. Material and methods: 10 unisex mongrel dogs were used in electrophysiological studies. Isolation of neural pathways in the pulmonary veins area were performed on epicardial or endocardial surface of opened heart, in 6 selected zones (1-3 in the right and 3-6 in the left side) by using the standard cl;inical method of RF ablation. Protocol of investigation included measuring of heart rate, sinus node (SN) function recovery time, AV node conductivity, and effective refractory periods of the atria, AV node and ventricles before and after isolation.
