Abstract

The electrophysiological properties of the atrioventricular conduction system were compared in 16 patients using stimulation of the high right atrium (HRA) and a site within the coronary sinus (CS). The site of atrial stimulation significantly altered A-V nodal conduction time and refractoriness in eight patients (Group A) and did not change A-V nodal properties in the remaining patients. His-Purkinje conduction time and refractoriness were not affected by changing the atrial stimulation site. The atrial stimulation site may influence A-V nodal function by changing the site and/or mode of entry of the impulse into the A-V node.
