Artificial cardiac pacemaker
Medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chambers (the upper, or atria and/or the lower, or ventricles) to contract and therefore pump blood.

Implantable cardioverter-defibrillator
An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
Heart block
Disorder in the heart's rhythm due to a fault in the natural pacemaker.
Despite the severe-sounding name, heart block may cause no symptoms at all in some cases, or occasional missed heartbeats in other cases (which can cause light-headedness, syncope (fainting), and palpitations), or may require the implantation of an artificial pacemaker, depending upon exactly where in the heart conduction is being impaired and how significantly it is affected.
Cardiac pacemaker
Initiated by electrical impulses known as action potentials.
In humans, and sometimes in other animals, a mechanical device called an artificial pacemaker (or simply "pacemaker") may be used after damage to the body's intrinsic conduction system to produce these impulses synthetically.
Electrocardiography
Process of producing an electrocardiogram , a recording of the heart's electrical activity.
Among other things, an ECG can be used to measure the rate and rhythm of heartbeats, the size and position of the heart chambers, the presence of any damage to the heart's muscle cells or conduction system, the effects of heart drugs, and the function of implanted pacemakers.
Bradycardia
Slow resting heart rate, commonly under 60 beats per minute (BPM) as determined by an electrocardiogram.
Treatment often consists of the administration of atropine and cardiac pacing.
Heart failure
Set of manifestations caused by the failure of the heart's function as a pump supporting the blood flow through the body; its signs and symptoms result from a structural and/or functional abnormality of the heart, that disrupts its filling with blood or its ejecting of it during each heart beat.
Sometimes, depending on the cause, an implanted device such as a pacemaker or an implantable cardiac defibrillator may be recommended.
Cardiac electrophysiology
Science of elucidating, diagnosing, and treating the electrical activities of the heart.
Other therapeutic modalities employed in this field include antiarrhythmic drug therapy and implantation of pacemakers and implantable cardioverter-defibrillators (ICD).
Medtronic
American medical device company based in Ireland for tax purposes.
The deficiencies of the artificial pacemakers of the day were made painfully obvious following a power outage over Halloween in 1957, which affected large sections of Minnesota and western Wisconsin.
Arrhythmia
Too fast or too slow.
Treatments may include medications, medical procedures such as inserting a pacemaker, and surgery.
Cardiac resynchronization therapy
Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the interior chest wall.
