Defibrillator

An implantable cardioverter defibrillator (ICD) is a small device that's placed in your chest or abdomen. This device uses electrical pulses or shocks to help control life-threatening, irregular heartbeats, especially those that could lead the heart to suddenly stop beating (sudden cardiac arrest). If the heart stops beating, blood stops flowing to the brain and other vital organs. This usually causes death if it's not treated in minutes.

Defibrillator Types

Several types of defibrillators are used to deliver electric currents to the heart muscles and correct abnormal and life threatening heart rhyt

Quick defibrillator shocks critical for cardiac arrest survival

It is well known that acting quickly in the event of a cardiac arrest is important, but what does a quick initial shock with a defibrillator mean exactly for patients' chances of survival? Researchers from Amsterdam UMC analyzed the data of 3723 patients who had a cardiac arrest outside the hospital and concluded that for the first shock, every minute reduces the chance of survival by 6%.

New defibrillation strategy could enhance survival rates in cardiac arrest

Joshua Lupton, M.D., has no memory of his own cardiac arrest in 2016. He only knows that first responders resuscitated his heart with a shock from a defibrillator, ultimately leading to his complete recovery and putting him among fewer than one in 10 people nationwide who survive cardiac arrest outside of a hospital.

Self-assembling heart stimulator can correct heart arrhythmia in emergency situations

By injecting a solution of nanoparticles around the heart, a temporary heart stimulator self-assembles, which can correct heart arrhythmia in emergency situations with the help of an external power source.

Rescue from above: How drones may narrow emergency response times

The drones are coming. Starting in September, if someone in Clemmons, North Carolina, calls 911 to report a cardiac arrest, the first responder on the scene may be a drone carrying an automated external defibrillator, or AED.

Preventive ventricular tachycardia ablation cuts down ICD shocks and hospitalizations

The first randomized trial to investigate preventive ablation of a potential arrhythmogenic substrate associated with coronary chronic total occlusion (CTO) in patients at high risk of ventricular arrhythmias (VAs) reduces the risk of appropriate implantable cardioverter-defibrillator (ICD) therapy and unplanned hospitalization in patients with no previously recorded VAs.

New cryoablation technique eliminates ventricular tachycardia in 94% of patients

A new technology using ultralow temperature cryoablation (ULTC) has eliminated clinical ventricular tachycardia (VT) in 94% of patients. The late-breaking science is presented at EHRA 2024, a scientific congress of the European Society of Cardiology (ESC).

Public defibrillators rarely used during cardiac arrest incidents, research shows

Automated external defibrillators (AEDs) are a common resource in public buildings, yet a new analysis reveals that they are rarely used to help resuscitate people suffering cardiac arrest.
