edit on Wikidata] Illustration of Implantable Cardioverter Defibrillator (ICD) 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.
Guided by anatomical landmarks and/or an X-ray image, the subcutaneous ICD electrode is tunneled under the skin. The subcutaneous ICD delivers therapy without the need for wires implanted in the heart. Depending on heart condition, 1, 2 or 3 leads will be placed in the heart.
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 .
Image showing the cardiac pacemaker or SA node, the primary pacemaker within the electrical conduction system of the heart The cardiac pacemaker is the heart 's natural rhythm generator. It employs pacemaker cells that produce electrical impulses, known as cardiac action potentials , which control the rate of contraction of the cardiac muscle ...
The technician or physician can download and review the recorded events during an office visit using a special programmer [4] or via online data transmission. [5] Remote control for a Biotronik implantable loop recorder used by the patient
More severe but relatively rare complications include: damage or trauma to a blood vessel, which could require repair; infection from the skin puncture or from the catheter itself; cardiac perforation, causing blood to leak into the sac around the heart and compromising the heart's pumping action, requiring removal using a needle under the ...

A wearable cardioverter defibrillator (WCD) is a non-invasive, external device for patients at risk of sudden cardiac arrest (SCA). [1] It allows physicians time to assess their patient's arrhythmic risk and see if their ejection fraction improves before determining the next steps in patient care.
