Abstract

Long QT syndrome is a cardiac disorder of repolarization which is characterized by electrocardiographic abn- ormalities including prolonged QT interval, T-wave abnormalities and polymorphic ventricular tachycardia known as Torsades de Pointes. Its clinical manifestations are recurrent syncope, seizure, and sudden death. Recently, we experienced Torsades de Pointes (TdP by head-up tilt test in 24 year-old female patient present- ing recurrent syncope and long QT interval. Beta-blocker and left cervicothoracic sympathetic ganglionectomy were not effective, then we tried mexiletine. After mexiletine medication, the QT interval was significantly shortened and there was no more syncope. ( ( ( (Korean Circulation J 2000;30( ( ( (8 :1040-1044
