Abstract
Quinidine, one of the first antiarrhythmic agents, has been associated with serious morbidity and mortality. Cardiac side effects include rhythm and conduction disturbances at both toxic and nontoxic levels. Extracardiac side effects include central nervous system, gastroenterological, and hematological toxicities. This case report illustrates one potential side effect of this antiarrhythmic drug in the treatment of atrial flutter and demonstrates one approach for differentiating supraventricular from ventricular wide complex tachycardias. The issues of prophylactic anticoagulation for converting atrial flutter to normal sinus rhythm and the future role of quinidine for the treatment of atrial arrhythmias are also discussed.
