2 heart block , clinically known as second-degree atrioventricular (AV) block, represents a specific category of cardiac conduction abnormalities where the electrical signals between the atria and ventricles are intermittently disrupted. This type of block suggests a block lower in the conduction system, often within the bundle branches of the His-Purkinje system.

This results in a mismatch where not every atrial contraction is followed by a corresponding ventricular contraction. Diagnosis and Risk Assessment.
It is frequently transient, caused by factors like increased vagal tone, certain medications, or acute myocardial infarction, and often resolves once the underlying trigger is addressed. In 2 heart block , this delay becomes pathological; the signal is either significantly slowed or completely blocked at this junction, preventing some atrial impulses from reaching the ventricles.

These impulses then reach the AV node, which briefly delays the signal to allow the atria to fully empty before the ventricles contract. Mobitz Type II Medical professionals classify second-degree AV block into two distinct types, which have vastly different implications for patient health and treatment urgency.
