A case of pacemaker and pacemaker-like syndrome.
This report describes the occurrence of both pacemaker syndrome and a pacemaker-like syndrome (so-called "pseudopacemaker syndrome") in a patient who exhibited an atrioventricular junctional rhythm probably on the basis of sick sinus syndrome. The clinical and hemodynamic manifestations of the two clinical situations were similar and associated with regular retrograde ventriculoatrial conduction. The abnormalities during the junctional rhythm were reproduced during ventricular pacing. Surprisingly, the occurrence of the pacemaker-like syndrome during junctional rhythm in patients with normal left ventricular function has rarely been described.
