Question

When the SA node sends an impulse and the AV node holds it for too long or sends it too quickly this is a ___________ __________?

Answer 1

A delay or quick transmittance of an impulse from the SA node to the AV node, resulting in a heart block or atrioventricular block, can occur in varying degrees and potentially disrupt heart function.

Step-by-step explanation:

When the SA node sends an impulse and the AV node holds it for too long or sends it too quickly, this is a type of heart block or atrioventricular block (AV block). A delay or quick transmittance of an impulse from the SA node to the AV node, resulting in a heart block or atrioventricular block, can occur in varying degrees and potentially disrupt heart function.AV blocks can occur in different degrees:

first-degree (or partial block), which shows a delay in conduction; second-degree (or incomplete block), where some but not all impulses pass through; and third-degree (or complete block), where no impulses pass from the atria to the ventricles. The severity of the symptoms depends on the degree of the block and can range from asymptomatic to life-threatening.
