Electrocardiogram Changes Suggestive of Coronary Artery Disease in Pneumothorax

Abstract

thorax is sought carefully, this diagnosis may be missed on physical examination. In recent months, we have seen several patients with pneumothorax in whom complaints of chest pain and dyspnea, coupled with an abnormal electrocardiogram, raised the diagnostic possibility of myocardial infarction. We wish to draw attention to the ECG abnormalities associated with pneumothorax and to the useful sign of normalization of the ECG when the patient is in the sitting position.
