How would a pacemaker affect someone after aortic valve replacement surgery?

Control pulse rate: Pacemakers are electrical stimulators used for bradycardia-slow pulse rate. After some cardiac operations, as well as spontaneous dysrhythymias-, slow and dangerous rates can occur. Pacemaker implants have become common and generally quite safe.

Synchronization: Allows for optimal heart function in the presence of complete heart block, sick sinus syndrome, chonotropic incompetence, symptomatic bradycardia to include some.
