A Young Woman With Recurrent Palpitations: A Case of Ebstein Anomaly With Mahaim Fiber Tachycardia

We present the interesting case of a young woman presenting with recurrent palpitations who was found to have Ebstein anomaly (EA) on transthoracic echocardiography with associated Mahaim fiber tachycardia on comprehensive electrophysiologic study (EPS). We discuss the pivotal role of echocardiography in clinching the diagnosis of EA and its influence on guiding appropriate therapy.
