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] Defibrillation delivers a dose of electric current (often called a counter-shock) to the heart Although not fully understood, this process depolarizes a large amount of the heart muscle, ending the arrhythmia Subsequently, the body's natural pacemaker in the sinoatrial node of the heart is able to re-establish
Defibrillators - What are Defibrillators? | NHLBI, NIH 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 resuscitation) and a defibrillator Some implantable or wearable defibrillators can also correct certain dangerous arrhythmias, which are problems with the
Implantable cardioverter-defibrillators (ICDs) - Mayo Clinic An implantable cardioverter-defibrillator, also called an ICD, is a small battery-powered device placed in the chest It detects and stops irregular heartbeats, also called arrhythmias An ICD constantly checks the heartbeat It delivers electric shocks, when needed, to restore a regular heartbeat

What is a Defibrillator? - News-Medical. net Defibrillation is a procedure used to treat life threatening conditions that affect the rhythm of the heart such as cardiac arrhythmia, ventricular fibrillation and pulseless ventricular tachycardia
Defibrillation: What Is A Defibrillator? How Does It Work To Revive . . . A defibrillator is a machine that delivers a controlled amount of electric current (called ‘countershock’ in medical lingo) to the heart A defibrillator is used when the heartbeat of the patient is erratic, or out of rhythm, if you will
