Abstract
Anomalous origin of coronary arteries is also a relatively rare congenital malformation and has been reported as the cause of angina pectoris and arrhythmia. Long QT syndrome (LQTS) is a rare inherited arrythmogenic disease characterized by susceptibility to lifethreatening arrhytmias andsudden cardiac death. We present a 36-year-old patient in whom two rare anomalies coexist and treated succesfully with β-blocker therapy.
