A 70-year-old woman with giant hiatal hernia presented with stable angina pectoris and three syncope attacks in the previous 3 months. Chest radiography showed marked cardiomegaly and an air-fluid level at the basal region of the heart. A mixed type large hiatal hernia that distorted the heart was detected in contrast-enhanced computed tomography and esophagogastroduodenography. Postprandial nonsustained ventricular tachycardia was present on 24-hour Holter ECG monitoring. The patient's symptoms were attributed to giant hiatal hernia and improved following surgery.
