One of the most dramatic and important differences between men and women regarding sex and arrhythmia is the greater risk in women of torsades de pointes induced by drugs that prolong repolarization [2]. Additionally, female gender is an independent risk factor for syncope and sudden death in the congenital long QT syndrome [3]. Although the molecular mechanisms for these sex-related differences are largely
