Implantable cardioverter-defibrillators (ICDs) - Mayo Clinic
Aug 15, 2023 · An implantable cardioverter-defibrillator (ICD) is a small battery-powered device placed in the chest. It detects and stops irregular heartbeats, also called arrhythmias. An ICD continuously checks the heartbeat. It delivers electric shocks, when needed, to …
Implantable Cardioverter Defibrillator (ICD) - American Heart Association
Oct 29, 2024 · What is an implantable cardioverter defibrillator? An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. Thin wires connect the ICD to your heart. If an abnormal heart rhythm is detected, the device will deliver an electric shock to restore a normal heartbeat.
Defibrillator: Types, Uses and Purpose - Cleveland Clinic
May 10, 2022 · A defibrillator is a device that provides an electric shock to your heart to allow it to get out of a potentially fatal abnormal heart rhythm, or arrhythmia, — ventricular tachycardia (with no pulse) or ventricular fibrillation — and back to a normal rhythm. Both of these arrhythmias happen in your heart’s ventricles or lower chambers.
Defibrillator Implant: Why It’s Done and What to Expect
Sep 28, 2022 · An implantable defibrillator is a small device inserted into the upper chest and heart to monitor it for dangerous arrhythmias. If it senses one, it will deliver a strong shock to get the rhythm back to normal.

Oct 6, 2023 · Implantable cardioverter defibrillator (Also known as ICD) — An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. If an ICD detects a heart rhythm that is chaotic or much faster than normal, it will send an electrical shock to the heart to bring the rhythm back to normal.
Heart Defibrillator: Uses, Implantation, ICD Longevity - Verywell …
Oct 23, 2023 · An implantable cardioverter defibrillator, or ICD, sends an electric shock to the heart to counteract a life-threatening abnormal heartbeat. It may be an option if you have had a heart attack or sudden cardiac arrest before or if you …
Implantable Cardioverter Defibrillator (ICD) - Cleveland Clinic
An implantable cardioverter defibrillator (ICD) is a medical device that monitors your heart and manages heart rate when needed. It’s surgically placed under your skin and connects to your heart with thin wires (leads). The battery-powered device can deliver an electric shock to correct life-threatening arrhythmia and prevent sudden cardiac arrest.
Defibrillation - Wikipedia
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1][2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
Defibrillators - What are Defibrillators? - NHLBI, NIH
Jun 6, 2023 · Defibrillators are devices that apply an electric charge or current to the heart to restore a normal heartbeat. If the heart rhythm stops due to cardiac arrest, also known as sudden cardiac arrest (SCA), a defibrillator may help it start beating again. A sudden cardiac arrest is fatal unless treated right away with CPR (cardiopulmonary ...
Defibrillators - How Do Defibrillators Work - NHLBI, NIH
Jun 6, 2023 · If a defibrillator detects a cardiac arrest or a dangerous arrhythmia, it can send an electric charge to the heart to try to restore a normal heartbeat or rhythm. This video explains your heart's electrical system and how an ICD can help prevent death from cardiac arrest and correct dangerous arrhythmias.
