Can the nervous system change the sequence of contractions of the atria and ventricles of the heart?

The nervous system is able to send impulses to muscles to contract. The heart is made up of muscle tissue. But the heart contracts without the participation of the nervous system. Nerve impulses arise in the heart itself. That is, the nervous system cannot influence the order in which the ventricles contract.
