[Long QT syndrome induced by cordaron and quinidine].

The article presents an observation of a 63-year-old female patient suffering from arterial hypertension, coronary artery disease complicated by a persistent form of atrial fibrillation during 1.5 months, and hereditary Minkowski-Chauffard hemolytic anemia. Treatment with cordaron proved to be ineffective, while oral administration of quinidin in a dose of 1 gr (0.2 gr five times a day) led to restoration of sinus rhythm. However, long QT interval syndrome complicated by ventricular tachycardic paroxysms of torsade de pointes type developed; later it transformed into ventricular fibrillation.
