Deep negative T waves associated with reversible left ventricular dysfunction in acute adrenal crisis

Abstract

We report two cases of reversible left ventricular dysfunction associated with deep negative T waves during acute adrenal crisis due to isolated deficiency of adrenocorticotrophic hormone. There were no symptoms suggestive of heart disease in either case and left ventricular wall motion abnormalities, present mainly around the left ventricular apex, returned to normal in 1-2 weeks. Deep negative T waves normalized 4 weeks after corticosteroid administration. Acute adrenal crisis should be considered when deep negative T waves are associated with left ventricular dysfunction without cardiac symptoms.
