Abstract
Pulmonary veins provide a favorable substrate for re-entry formation. Heterogeneity of the electrophysiologic properties and marked abbreviation of action potential duration and refractoriness by acetylcholine combine to produce rapid and stable re-entrant PV tachycardias. Elevated parasympathetic tone and re-entrant PV tachycardia may serve as a mechanism underlying the perpetuation of PAF.
