Sinus arrest associated with dipyridamole infusion.
We describe a case of prolonged sinus arrest resolved by external cardiac massage following intravenous infusion of dipyridamole, during a thallium myocardial perfusion test. The arrhythmia, presumably due to an acute drug adverse effect, had not been previously described (to our knowledge) as a complication of dipyridamole stress testing.
