<P> The AV node functions as a critical delay in the conduction system . Without this delay , the atria and ventricles would contract at the same time , and blood would n't flow effectively from the atria to the ventricles . The delay in the AV node forms much of the PR segment on the ECG , and part of atrial repolarization can be represented by PR segment . </P>
