Cardiovascular Consequences of Anorexia Nervosa: QT Prolongation, Bradycardia, and Structural Cardiac Changes

Anorexia nervosa (AN) is a severe psychiatric disorder with profound cardiovascular consequences, including QT interval prolongation and bradycardia. These abnormalities contribute to an increased risk of life-threatening arrhythmias, sudden cardiac death, and long-term cardiac dysfunction. Although electrolyte imbalances and malnutrition are also recognized as key contributors, the precise mechanisms underlying…

Sudden Cardiac Death

Sudden cardiac death (SCD) due to ventricular tachyarrhythmias is a leading cause of death in the United States. Various etiologies, including ischemic and nonischemic cardiomyopathies, hypertrophic cardiomyopathy, valvular or congenital heart diseases and other less common disorders, may result in SCD. Beta blockers are the only class of medications that…

Brugada Syndrome Mimicking Acute Coronary Syndrome

This report describes a 42-year-old man with Brugada syndrome (BRS) mimicking acute coronary syndrome. Chest pain, near-syncope, and electrocardiographic changes were thought initially to be due to ischemia. Cardiac catheterization was performed. The coronary arteries and left ventricular function were normal. Careful review of his electrocardiogram suggested a diagnosis of…
