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. 4 We reviewed the literature and found only 4 documented cases of complete heart block associated with influenza virus infection. 5–8 In 2 of those cases, the changes were transient. 7,8 We present the cases of 2 patients with influenza who developed high-grade atrioventricular (AV) block; in one patient, the block atrioventricular block, third degree see atrioventricular 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. 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.

Atrioventricular (AV) blocks occur due to dysfunction in the conduction system. The atrioventricular (AV) node is richly innervated with sympathetic and parasympathetic fibers. Understanding Atrioventricular Block AV blocks are conduction delays or a complete block of impulses from the atria into the ventricles.

Heart block (atrioventricular block) Bradycardia can also occur because electrical signals transmitted through the atria aren't transmitted to the ventricles (heart block, or atrioventricular block). Heart blocks are classified based on the degree to which signals from the atria reach your heart's main pumping chambers (ventricles).
