Which term is used for the device that provides artificial electrical impulses to the heart muscle when needed?

• A. Leads
• B. NSR
• C. Pacemaker
• D. Polarization

Answer: (C)

A pacemaker is the device that provides artificial electrical impulses to the heart when needed. It delivers timed electrical signals to stimulate heartbeats, helping regulate a heart that is too slow or has conduction problems. The device itself is the pulse generator, often with leads that connect to the heart muscle to deliver the impulses. Leads are just the wires that carry the impulses, not the device. NSR (normal sinus rhythm) describes a normal heart rhythm, not a device. Polarization refers to the electrical state of heart tissue, not a pacing device. So the correct term for the device that supplies artificial impulses is pacemaker.
