Pathophysiology
First degree AV block may be due to conduction delay in the AV node, His-Purkinje system (made up by the bundle of His and the Purkinje fibers), or a combination of the two. The majority of cases are due to a dysfuction of the AV node; however, when first degree heart block coexists with a bundle-branch block, the cause is more likely to be a conduction delay in the His-Purkinje system. There are no missed beats in first degree AV block and all the impulses from the atria are transmitted to the ventricles resulting in a regular ventricular beat rhythm.
