Inverted T waves in patient with Addisonian crisis.

Addisonian crisis represents a state of acute adrenocortical insufficiency and occurs in patient with Addison's disease who are exposed to stress of infection, surgery, trauma, vomiting and diarrhea. We present a case with a 39-year-old female patient who admitted to the hospital with Addisonian crisis and, interestingly, her electrocardiograph showed ST depression and inverted T waves on inferior and V4-V6 leads. She did not have a history of angina pectoris and coronary artery disease, and her cardiac enzymes were normal. Exercise stress testing and echocardiographic assessment revealed normal findings. When faced with such a patient who has hypotension and ischemic ECG changes without having underlying angina, Addisonian crisis should be considered in differential diagnosis.
