title: Irregular pacemaker tachycardia in a patient with WPW syndrome and an A-V universal pacemaker.
abstract: We describe a case of an irregular pacemaker circus movement tachycardia in a patient with the Wolff-Parkinson-White syndrome and a normally functioning A-V universal (DDD) pacemaker (Cordis Sequicor 233 D). The mechanism of the artificial circus movement tachycardia, which uses the pacemaker as the anterograde limb and a septally located accessory atrioventricular pathway as the retrograde limb, is discussed.
