Popis:	Papaverine, a potent coronary vasodilator, is now commonly used to measure coronary reserve. We recorded intracoronary electrogram in a patient who developed Torsade des pointes after 10 mg of papaverine. This was associated with marked prolongation of the QT interval. The ventricular tachycardia self-terminated with shortening of the QT interval. We believe that although papaverine is a good agent because of its short duration of action, it must be used cautiously because of its effects on repolarization, which can result in arrhythmias.
