The blocking of the impulse can come and go, resulting in “dropped heartbeats.” A second-degree type II block may progress to complete or third-degree heart block. Second-degree heart block can be categorized into two types: Mobitz type I block (also called Wenckebach) usually occurs in the AV node.

Can heart block reversed?
Complete atrioventricular (AV) block is known to be reversible in some cases of acute inferior wall myocardial infarction (MI). The reversibility of high-grade AV block in non-MI coronary artery disease (CAD), however, is rarely described in the literature.
