Atrial fibrillation after intravenous dipyridamole for thallium imaging.
Dipyridamole 0.56 mg/kg was administered intravenously for thallium tomography after myocardial infarction. Fast atrial fibrillation developed which failed to resolve with aminophylline. Sinus rhythm returned within 3 days. Myocardial tomography revealed apical infarction without reversible ischaemia. Atrial fibrillation after dipyridamole is rare and may be caused by direct electrophysiological effects on the atrial myocardium.
