Why the study?
Does His bundle electrocardiography help define the function of the conduction system in a patient with a single ventricle and 2:1 block?
Does His bundle electrocardiography help define the function of the conduction system in a patient with a single ventricle and 2:1 block?
His bundle electrocardiography can effectively define the location of conduction blocks and identify abnormal accessory pathways in patients with single ventricle physiology.

May localize AV block and accessory pathways in single ventricle; hypothesis-generating and should not yet change practice.
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.
