Question

Why is there a delay in the transmission of Impulse from SAN to ventricles provided by AVN?

Answer 1

Avn (Avascular necrosis)

1. The death of bone tissue due to a lack of blood supply is known as avascular necrosis (AVN).
2. Osteonecrosis, aseptic necrosis, and ischemic bone necrosis are all terms used to describe this condition.
3. The simultaneous contraction of auricles and ventricles is prevented by a delay in the transfer of impulses from SAN to the ventricles rendered by AVN.
4. This allows the atria to drain entirely before the ventricles collapse.
