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). If you have heart block, the electrical signal from the AV node to the ventricles that controls your heartbeat is partly or completely blocked from reaching the ventricles.

There are three types of atrioventricular (AV) block based on the severity of the conduction abnormality: (1) first‐degree AV block; (2) second‐degree AV block which includes mobitz type I (also called AV Wenckebach), mobitz type II, 2:1 fixed‐ratio AV block, and high‐grade (also called advanced) 2nd degree AV block; and (3) third‐degree or complete AV block. However, none of those findings were considered clinically significant.

From Wikipedia, the free encyclopedia First-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart in which electrical impulses conduct from the cardiac atria to the ventricles through the atrioventricular node (AV node) more slowly than normal.

Atrioventricular (AV) block is a cardiac electrical disorder defined as impaired (delayed or absent) conduction from the atria to the ventricles. The severity of the conduction abnormality is described in degrees: first-degree; second-degree, type I (Wenckebach or Mobitz I) or type II (Mobitz II); and third-degree (complete) AV block.

There are three degrees of AV block, categorized according to the extent of the delay or interruption. First-degree blocks are identifiable on ECG by a prolonged PR interval.

Non-conducted P waves (not followed by QRS complexes) can be seen on the electrocardiogram. What is atrioventricular block? AV block can be defined as a delay/interruption in the transmission of an electrical impulse from the atria down to the ventricles.

Since its first description by Hays in England in 1906, second-degree atrioventricular (AV) block has been a fascinating clinical entity, mainly due to obscure points regarding its diagnosis that emanate from misconceptions and errors regarding its proper definition.1–3 The practicing clinician should be aware of the following points that may assist a proper diagnosis and, consequently

Diagnosis is by electrocardiography; symptoms and treatment depend on degree of block, but treatment, when necessary, usually involves pacing. Atrioventricular (AV) block can be described by degree (based on ECG appearance) or by anatomic level of block. The degree of AV block or anatomic level of block does not necessarily correlate with the severity of subsequent symptoms. First-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart in which electrical impulses conduct from the cardiac atria to the ventricles through the atrioventricular node (AV node) more slowly than normal.
