T wave alternans associated with amiodarone.
T wave alternans is an intriguing phenomenon widely observed in some experimental conditions, but rare in clinics. The authors describe a case of T wave alternans associated with amiodarone treatment. This electrocardiographic finding spontaneously reverted and was not associated with ventricular arrhythmias or hemodynamic depression. Mechanisms that may be responsible for alternation of the T wave are discussed.
