A 79-year-old woman was admitted due to chest pain with T wave inversion and anasarca. Echocardiography demonstrated a mass compressing the heart and computed tomography revealed a giant hiatal hernia within the intrathoracic stomach located just behind the heart. After drainage of the gastric contents, the T wave inversion disappeared, but subsequent ST elevation in leads V1-V6 was noted. After surgical correction of the hiatal hernia, the ST segment elevation returned to a nearly normal level. The changes in the compressed heart induced by hiatal hernia may cause pericarditis resulting in electrocardiographic changes.
