Arrhythmias in single-chamber pacemakers.

Arrhythmias mediated by normal pacemaker functions and induced by pacemaker malfunctions are listed in Tables 1 and 2. Frequently, a careful review of the performance specifications in the technical or physician manual of the pacemaker model in question will provide a better understanding of pacemaker-related arrhythmias. By reprogramming selected parameters, the physician may eliminate the arrhythmia and avoid replacement of a normally functioning pulse generator.
