Pacing induced ventricular fibrillation in internal cardioverter defibrillator patients: a new form of proarrhythmia.
Current model internal cardioverter defibrillators (ICDs) have cardioversion, defibrillation, pacemaker, and telemetry function. Telemetry documents arrhythmia and facilitates therapeutic adjustments. We report two cases of pacing induced VF terminated by the defibrillator, with the device responsible for both initiation and correction of the arrhythmia.
