Abstract
The presence of ST-segment elevation on the electrocardiogram alerts physicians in patients with chest pain. Emergency coronary angiography is usually performed in these patients. However, there are many conditions that cause ST-segment elevation on the electrocardiogram, such as pericarditis, hyperkalemia, Brugada syndrome, hypothermia, and early repolarization. Pneumothorax is a rare complication of tracheostomy and its symptoms are sudden chest pain and dyspnea. Also, it has been known that pneumothorax may cause ST-segment changes on the electrocardiogram. We presented a transient inferolateral ST-segment elevation on the electrocardiogram due to an iatrogenic left-sided pneumothorax after an urgent tracheostomy in a patient with metastatic hypopharynx cancer and normal coronary angiogram.
