Transient sinus node dysfunction with acute hepatitis of unknown etiology

Abstract

We reported a case of a 72-year-old male, known diabetic on insulin, referred because of complete atrioventricular block. He was found to have acute hepatitis during which he developed transient atrial arrhythmia, and sinus node dysfunction. His cardiac symptoms disappeared completely after hepatitis improvement. All of his cardiac investigations were normal including electrocardiogram, echocardiography and thalium stress test. At 3 and 6 months follow up, his Holter monitoring did not show any further arrhythmia, and he denied any further episodes of palpitation or pre-syncope. We reviewed the literature regarding the relationship between hepatitis and atrial arrhythmia.
