Atrioventricular conduction block

特許 係属中 An atrioventricular block (or AV block) involves the impairment of the conduction between the atria and ventricles of the heart. Under normal conditions, the SA node in the atria sets the pace for the heart, and these impulses travel down to the ventricles. In an AV block, this message does not reach the ventricles or is impaired along the way.
