A system that sends electrical impulses to the heart in order to set the heart rhythm. The pacemaker can be the normal "natural" pacemaker of the heart or it can be an electronic device. The natural pacemaker of the heart is the sinus node, one of the major elements in the cardiac conduction system, the system that controls the heart rate [..]

A pacemaker in which the electrodes to the heart, the electronic circuitry, and the power supply are all implanted internally within the body.

A device that uses electrical impulses to regulate the heart rhythm or to reproduce that rhythm. An internal pacemaker is one in which the electrodes into the heart, the electronic circuitry and the power supply are implanted (internally) within the body. Although there are different types of pacemakers, all are designed to treat bradycardia, a hea [..]

An electronic device that is implanted in the body to monitor heart rate and rhythm. It gives the heart electrical stimulation when it does not beat normally. It runs on batteries and has long, thin w [..]

A specialized region of the right atrium of the mammalian heart that sets the rate of contraction; also called the sinoatrial (SA) node. See Sinoatrial node.

See cardiac pacemaker.

also pace-maker, 1884, originally a rider or boat that sets the pace for others in training. Meaning "the node of the heart which determines the beat rate" is from 1910; sense of "man-m [..]

electronic device implanted beneath the skin to regulate a person's heartbeat.

An abbreviation for ‘cardiac pacemaker’. It is a small device implanted in the heart that consists of electrodes. The electrodes emit electrical impulses to regulate the beating of the heart.

A device used when your heart impulses do not work properly. It is implanted in your chest and sends electrical impulses to make your heart contract.

(p=as´ma´´ker) A group of cells that has the fastest spontaneous rate of depolarization and contraction in a mass of electrically coupled cells; in the heart, this is the sinoatrial, or SA, node. pacinian corpuscle

noun. a natural or faux gadget which assists in establishing and preserving specific biological rhythms.

pacemaker (pop)

A group of cells, known as the sinoatrial node, that are located in the atrium of the heart and serve to regulate the rate and rhythm of the heart. An artificial cardiac pacemaker is an electrical dev [..]

controls the pace at which the heart beats.

(n) a leading instance in its field(n) a specialized bit of heart tissue that controls the heartbeat(n) an implanted electronic device that takes over the function of the natural cardiac pacemaker(n)  [..]

A small electronic device generally placed in the chest to correct an irregular heartbeat. It generates small electrical pulses that prompt the heart to beat at a normal pace.

A specialized cluster of cells called the sinoatrial node in the top of the right atrium. The pacemaker produces a steady flow of beat now signals that flash across the atria and then pass through the [..]

is a mechanical device that uses electrical impulses delivered to the heart muscle to generate a contraction or heartbeat.

Artificial Pacemakers with implantable leads to be placed in the RIGHT ATRIUM and both Heart Ventricles. They are used to treat various cardiac conduction disturbances which interfere with the timing [..]

A device designed to stimulate, by electric impulses, contraction of the Heart Muscles. It may be temporary (external) or permanent (internal or internal-external).

A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external).

A pacemaker is a small, lightweight electronic devise that is prescribed for people whose hearts are beating too slowly. It is implanted into the body, usually in the upper chest, near the shoulder. T [..]

An electronic device that is implanted in the body to monitor heart rate and rhythm. It gives the heart electrical stimulation when it does not beat normally. It runs on batteries and has long, thin wires that connect it to the heart. Also called artificial pacemaker and cardiac pacemaker.

the group of specialized heart cells that control the heartbeat

One who sets the pace in a race, to guide the others. (anatomy) A set of nerves which stimulate the heart to beat. (hence,medicine) A medical implement that is used to stimulate a heart to beat [..]

A pacemaker is a small electronic device implanted in the chest to help the heart beat regularly. If you have a pacemaker, you cannot have an MRI scan because these scans are magnetic and interfere with how your pacemaker works.

a battery-driven, mechanical device used to treat heart rhythms that are too slow, too fast or irregular. The battery and electrical circuits ("generator") are implanted in the body, usually [..]

A small, implantable device that provides an electrical stimulus to the heart when the natural electrical signal is absent or too slow to provide sufficient pumping action. Parasympathetic Nervous Sys [..]
