Based on your knowledge of the heart’s electrical system, what will happen if a patient’s primary pacemaker fails?
Another area of the electrical system will initiate a heartbeat.
The atria will stop contracting, but the ventricles will continue to contract.
The patient will go into cardiac arrest.
