S-ICD lead and generator position Sketch of an already-implanted cardioverter ...
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .
As with conventional pacemaker therapy, the cardiac contractility modulation device cannot be implanted if the leads cannot be positioned appropriately in the heart. In cases where there is an artificial heart valve between the right atrium and ventricle (a mechanical prosthetic tricuspid valve), the valve function could be greatly affected by ...
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...

AICD: Patients with NYHA class II, III or IV, and LVEF of 35% (without a QRS requirement) may also benefit from an implantable cardioverter-defibrillator (ICD), a device that is proven to reduce all-cause mortality by 23% compared to placebo in patients who were already optimally managed on drug therapy.

Pacemaker: Coordinates contractions between ventricles. In people at risk of arrhythmias, drug therapy or an implantable cardioverter-defibrillator (ICD). ICDs: Small devices implanted in the chest to monitor heart rhythm and deliver electrical shocks to control abnormal heartbeats. The devices can also work as pacemakers.
