title: Demonstration of abnormal proximal conduction system by His bundle electrocardiography in a patient with a single ventricle.
abstract: His bundle electrocardiography in a patient with a single ventricle and 2:1 block showed the block to be proximal to the His bundle. The sinus node recovery time was normal. In addition, there was suggested evidence of a functionally and/or structurally abnormal accessory pathway. The role of His bundle electrocardiography in a patient with a single ventricle in defining the function of various portions of the conduction system was thus demonstrated.
