Pseudo Atrioventricular Block

Pseudo first- and second-degree atrioventricular (AV) block can occur due to depressive effects of concealed junctional discharges on AV conduction of sinus impulses. Pseudo AV block is not indicative of a primary impairment of AV conduction and is reversible by interventions that suppress ectopy. ( Arch Intern Med 139:459-460, 1979)
