pacemaker

[′pās‚māk·ər]
(medicine)
A pulsed battery-operated oscillator implanted in the body to deliver electric impulses to the muscles of the lower heart, either at a fixed rate or in response to a sensor that detects when the patient's pulse rate slows or ceases. Also known as cardiac pacemaker; heart pacer.

The dual-chamber pacemaker significantly reduces unnecessary pacing in the right ventricle by offering a pacing mode--called managed ventricular pacing (MVP)--that enables the device to be programmed to deliver pacing pulses to the right ventricle less than 2% of the time.
Patients with a dual-chamber pacemaker had a 36% increased risk of these outcomes, suggesting that pacing both the right atrium and ventricle may be less hazardous than pacing the right ventricle alone.
