These AV heart blocks include: AV 1st degree, Mobitz I (Wenckebach) 2nd Degree Type 1, Mobitz II 2nd Degree Type 2, and 3rd degree (complete heart block).

Second-degree AV block Mobitz type I exhibits the Wenckebach phenomenon, which means that there are ECG signs of gradual exhaustion of impulse conduction. ECG Examples. Example 1. Marked first degree heart block. PR interval > 300 ms, P waves are buried in the preceding T wave.

Conduction system blocks may occur in the atrioventricular node, His bundle, or His-Purkinje system, or at multiple  1st Degree AV Block.

The atrial depolarization In third-degree (complete) atrioventricular block, there is a total interruption of AV conduction, causing an electrical disconnection between the atria and the ventricles. No stimulus is transmitted through the AV conduction system, so the atria and ventricles are depolarized independently of each other 1 2. 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.

Diagnosis is by electrocardiography; symptoms and treatment depend on degree of block, but treatment, when necessary, usually involves pacing. The condition is also called atrioventricular (AV) block. The AV node is a cluster of cells that connects the electrical activity in the top chambers of the heart (atria) to the bottom chambers of the heart (ventricles).
