The impact in this case is the ventricles will beat more slowly.

Sinoatrial node acts as a pace maker for the heart skipping the plateau phase and the electric impulses are created here. This node lets the blood into ventricles.

Atrioventricular node acts as controller of heart rate and serves as an electrical relay station. This node connects the right atrium and right ventricle.
