title: Atrial fibrillation induced by testing magnet applied to VVI pacemaker.
abstract: The first known case of testing magnet-induced atrial fibrillation in a patient with a VVI pacemaker is reported. A macrore-entry mechanism is postulated, involving retrograde conduction from the ventricle through the AV node to the atrium following an asynchronous pacemaker stimulus.
