Adenosine can produce arrhythmias, which are generally short living. It may induce PACs and PVCs, sinus bradycardia, and atrial fibrillation. There have been reports of transient polymorphic VT (torsades de pointes) in patients with LQTS and others in people with normal QT interval. We report a case of a long episode of polymorphic VT induced by adenosine. A 27 year old woman received 6 mg adenosine for PSVT, which terminated and torsades de pointes developed, persisting for 17 seconds and terminated spontaneously. This is the longest described duration of the torsades after adenosine administration in patients with normal QT interval.
