Torsades de Pointes. Torsades de pointes are typically characterized by an ECG pattern of polymorphous but organized electrical activity of ventricular origin that occurs in the setting of a long QT interval, long‐coupled bigeminy, and has specific precipitating causes and therapeutic responses. Torsades de pointes can result from congenital (adrenergic dependent) and acquired (pause dependent) factors and may have similar cardiac substrates with different precipitating events.
