Why the study?
Can His bundle electrograms characterize the specific site and type of conduction disturbance in patients with heart block?
Can His bundle electrograms characterize the specific site and type of conduction disturbance in patients with heart block?
His bundle electrograms are useful for localizing the specific site of conduction block in patients with heart block.
Answers are grounded in this paper and cite their sources.
His bundle electrograms may localize conduction blocks; hypothesis-generating from case data and requires validation before wider use.
A total of 24 patients with heart block revealed by scalar electrocardiography was studied using the His bundle electrogram. Four groups of disturbed conduction are described which include various types of heart block, partial and complete, at different sites, single and multiple, in the specialized conducting system. These are (i) intra-atrial block with delayed or blocked internodal conduction, (2) atrioventricular nodal block due to delayed or blocked conduction in the A V node, Received 2 December 197r.
