title: Diffuse T-wave inversions associated with electroconvulsive therapy.
abstract: Electroconvulsive therapy (ECT) can lead to ST depression and arrhythmias in patients with coronary artery disease, most likely secondary to increased myocardial oxygen demand. This report describes a case of ECT-associated, global T-wave inversions in a patient with chronic atrial fibrillation treated with digoxin. Laboratory evaluation and echocardiography were normal. These T-wave changes may result from increased sympathetic activity associated with ECT. Prospective studies suggest that this finding may be seen in up to 4% of patients undergoing ECT.
