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.
S-ICD lead and generator position. 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]
A wearable cardioverter defibrillator is a portable external defibrillator that can be worn by at-risk patients. [21] The unit monitors the patient 24 hours a day and can automatically deliver a biphasic shock if VF or VT is detected. This device is mainly indicated in patients who are not immediate candidates for ICDs. [22]
Amiodarone is also commonly used as the first-line therapy for patients who receive shocks from implantable cardioverter defibrillators caused by ventricular arrhythmias. Combining amiodarone with beta-blockers has been shown to reduce the likelihood of experiencing inappropriate shocks from implantable cardioverter defibrillators.
An implantable cardioverter-defibrillator (ICD) is a battery-powered device that monitors electrical activity in the heart, and when an arrhythmia is detected, can deliver an electrical shock to terminate the abnormal rhythm. ICDs are used to prevent sudden cardiac death (SCD) in those who have survived a prior episode of sudden cardiac arrest ...
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]
An ICD (implantable cardioverter defibrillator) is more effective than drug therapy for prevention of sudden cardiac death due to VT and VF, but does not prevent these rhythms from happening. Catheter ablation is a potentially definitive treatment option for those with recurrent VT. [18]
Implantable devices such as the artificial cardiac pacemaker and implantable cardioverter-defibrillator are capable of measuring a "far field" signal between the leads in the heart and the implanted battery/generator that resembles an ECG signal (technically, the signal recorded in the heart is called an electrogram, which is interpreted ...
