[Anti-arrhythmia therapy in emergencies--lidocaine versus ajmaline]

Abstract

Up to now lidocain was regarded as remedy of first choice in life-threatening ventricular arrhythmias. According to more recent investigations in the emergency situation ajmalin showed itself superior to lidocain in the treatment of ventricular tachycardias. For the prophylaxis of primary ventricular fibrillation lidocain is still recommended, though despite numerous studies an effectiveness is not verified. The treatment of the primary ventricular fibrillation should always be performed by defibrillation as far as possible. The earlier it is performed the more successful is the measure. If a defibrillator is not at disposal an attempt with lidocain or ajmalin can bie made.
