During complete heart block (third-degree AV-block) the block may be located anywhere between the atrioventricular node and the bifurcation of the bundle of His. If there are cells (with automaticity) distal to the block, an escape rhythm may arise in those cells. For example, consider a complete block located in the atrioventricular node.
