Diseases associated with infiltration of spiriva muscle with pathological tissues that make it difficult to conduct through the AV node: sarcoidosis; hypothyroidism; hemochromatosis; Lyme disease; endocarditis. The degree of AV conduction can also be affected by systemic diseases: ankylosing spondylitis and Reiter's syndrome.
First-degree atrioventricular block may result from delayed conduction in the atrium, AV node, bundle of His, or pedicles. The dominant site of impulse delay is the AV node (in 83% of patients). Atrial or AV node conduction delay in grade I AVB is transient or stable and may slowly progress towards higher degrees of AV block.
