Case Reports
ST segment elevation on electrocardiogram: the electrocardiographic pattern of Brugada syndrome.
A 77-year-old white diabetic woman was brought to our emergency department (ED) after becoming lightheaded and hypotensive at home. Her routine tests including a chest radiograph were normal. Her electrocardiogram (ECG) showed significant ST segment elevation in leads V1 to V4. ⋯ To diagnose the Brugada syndrome, 1 ECG criterion and 1 clinical criterion should exist. Brugada syndrome can be associated with ventricular tachycardia or fibrillation; the only treatment proven to prevent sudden death is placement of an implantable cardioverter defibrillator, which is recommended in symptomatic patients or in those with ventricular tachycardia induced during electrophysiologic studies and a type 1 ECG pattern of Brugada syndrome. It is important to recognize the Brugada ECG pattern and to differentiate it from other etiologies of ST segment elevation on ECG.

Secondary aortoenteric fistula (SAF) is an uncommon but very important complication of abdominal aortic reconstruction. The complication often occurs months to years after aortic surgery. The clinical manifestation of the aortoenteric fistula is always upper gastrointestinal bleeding. ⋯ The patient did well after the surgical management. Because of the increasing number of elective aortic aneurysm repairs in the aging population, it is likely that more patients with secondary aortoenteric fistula will present to the clinical physicians in the future. So, a high index of suspicion is necessary for prompt diagnosis and treatment of this life-threatening event.
