Second-degree Atrioventricular Block
Second-degree AV block is a disease of the electrical conduction system of the heart. It refers to a conduction block between the atria and ventricles.
The presence of second-degree AV block is diagnosed when one or more (but not all) of the atrial impulses fail to conduct to the ventricles due to impaired conduction.
