[Quinidine-induced syncope simulating transient cerebral ischemic attack].

A case of quinidine-induced syncope with prevailing neurological symptoms is reported in which the transient right-sided hemiparesis and fluctuating soporific state was induced by recurrent torsades de pointes ventricular tachycardias. In connection with this case, attention is paid to the difficulties of differential diagnosis and to the consideration of cardiac and metabolic disorders mimicking TIA or ischaemic stroke.
