A case of severe myocardial ischaemia complicated by syncopal ventricular tachycardia during injection of Dipyridamole for stress Thallium myocardial scintigraphy in a coronary patient is reported. Myocardial ischaemia (chest pain, ECG changes) is classically rare (30% of cases) and usually benign during Dipyridamole injection, and either regress spontaneously or after administration of Theophylline. However, the possibility of serious complications such as this justifies the same criteria of strict surveillance as for classical exercise stress testing.
