title: Wolff-Parkinson-White bigeminal pattern after administration of tensilon.
abstract: A rare case of WPW bigeminal pattern was recorded in a 53-year-old man. This electrocardiographic pattern occurred after 10 mg tensilon was given intravenously to suppress a supraventricular tachycardia. WPW bigeminal pattern was terminated after intravenous administration of 100 mg lidocaine and the occurrence of a PVB. We assume that tensilon inducing a vagal effect on the anomalous pathway and changes in the heart rate has caused WPW bigeminal pattern.
