Pacemaker bigeminy: pseudomalfunction.
The first reported unique case of atrial synchronized pacemaker-induced bigeminy is described and related literature is briefly discussed. The arrhythmia reported in this case can be erroneously misinterpreted as a malfunctioning pacemaker unless the physician is fully familiar with the specific nature of the atrial synchronized pacemaker. By recognizing this type of pacemaker bigeminy as an arrhythmia simply related to a normally functioning pacemaker, unnecessary surgery can be avoided.
