Abstract

The aim of the present study was experimental demonstration of the formation of reentry in isolated preparations of the rabbit's right atrium, including sulcus terminalis, interatrial septum and AV node. Tachycardia was evoked by extrasystolic stimulation of the preparation. Reentry was identified by computerized multichannel mapping of excitation wave propagation. A series of sections performed in the area between the caval veins and the coronary sinus confirmed the presence of reentry pathway round the orifices of caval veins and through AV made zone. Local cooling and sections performed in different parts of the AV node showed that not all areas of AV node were involved in the formation of reentry, but only the perinodal (AN) area. These effects on the AN area terminated tachycardia. Linear dependence between the period of tachycardia and delay in the AV nodal zone was found.
