An 86-year-old man presented with sudden onset of dyspnea during hospitalization. Initial electrocardiography (ECG) showed poor R-wave progression of precordial leads with elevation of troponin I. Tension pneumothorax was subsequently diagnosed and the ECG returned to normal after resolution of clinical compromise.
