First-degree atrioventricular (AV) block occurs when there is a delay in the impulse transmission at the AV node. This delay occurs with every impulse and can be seen on every beat on the recorded rhythm strip. Second-degree and complete heart block have differences with the P wave and the associated QRS complexes.
