What Is a Bundle Branch Block?
Bundle Branch Block . Rate variable P wave normal if the underlying rhythm is sinus QRS wide; > 0.12 seconds Conduction This block occurs in the right or left bundle branches or in both. The ventricle that is supplied by the blocked bundle is depolarized abnormally. Rhythm regular or irregular depending on the underlying rhythm.
