Abstract

A unique case of heretofore undescribed 2:1 ventricular electrical alternans in the presence of artificial pacemaker-induced ventricular rhythm is presented. Three instances of 2:1 ventricular pseudo-electrical alternans due to ventricular fusion bigeminy in patients with permanent demand pacemakers are also discussed.
