in the interventricular septum
Explain the reason there is a delay in processing the electrical signal from the AV node to the AV bundle. To:
allow the atria to complete their contraction prior to ventricular contraction
ensure the right and left atria contract at the same time
ensure the right and left ventricles contract at the same time
prevent an ectopic pacemaker
