Second-Degree Atrioventricular (AV) Block, Second-Degree Heart Block

Definition

Second-degree atrioventricular (AV) block, also known as second-degree heart block, is a type of heart block characterized by the intermittent disruption of electrical signals between the atria and ventricles of the heart. This can result in a slower or irregular heartbeat, potentially leading to inadequate blood flow to the body.
