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.
Subcutaneous implantable cardioverter defibrillator, or S-ICD, is an implantable medical device for detecting and terminating ventricular tachycardia and ventricular fibrillation in patients at risk of sudden cardiac arrest. [1]
Implantable cardioverter-defibrillators (ICD) are electronic devices implanted in the chest with a lead to the right ventricle of the heart. They are intended for patients with permanent risk for SCD. An ICD is, like a WCD, designed to detect and terminate cardiac arrhythmias by emergency defibrillation. [37]
Implantable cardioverter-defibrillators, also known as automatic internal cardiac defibrillator (AICD), are implants similar to pacemakers (and many can also perform the pacemaking function). They constantly monitor the patient's heart rhythm, and automatically administer shocks for various life-threatening arrhythmias, according to the device ...
Implantable cardioverter defibrillator (a device that shocks your heart into a normal rhythm when needed) ... When heart arrest occurs outside of a hospital, the main treatment is a shock with an ...
The leads are attached to electrodes that monitor the electrical activity in the heart. When irregular electrical activity is detected in the heart, the defibrillator delivers a shock to restore normal electrical activity. The automatic implantable cardioverter defibrillator is the size of a deck of cards and weighs nine ounces.
CRT defibrillators (CRT-D) also incorporate the additional function of an implantable cardioverter-defibrillator (ICD), to quickly terminate an abnormally fast, life-threatening heart rhythm. CRT and CRT-D have become increasingly important therapeutic options for patients with moderate and severe heart failure. [ 3 ]
A specific type of pacemaker, called an implantable cardioverter-defibrillator, combines pacemaker and defibrillator functions in a single implantable device. [5] Others, called biventricular pacemakers, have multiple electrodes stimulating different positions within the ventricles (the lower heart chambers) to improve their synchronization. [6]
