Retrograde block during atrioventricular (AV) nodal reentrant tachycardia is considered a rare phenomenon that can potentially occur in the AV node or in the atrium. A patient with slow-fast AV nodal reentrant tachycardia and transient VA block localized in the AV node is presented. Pharmacological and stimulation maneuvers identified the site of block in the AV node and not in the atrium. Thus, AV nodal reentry can be confined to the AV node.
