Defibrillators (ICD) is a battery-operated device placed under your skin to keep track of your heart rate. Whenever an abnormal heart rhythm is detected the device delivers an electric shock in order to restore the normal heartbeat if your heart is beating chaotically or much too fast.
Persons who may have a Sudden Cardiac Arrest (SCA) are the ones who need a defibrillator. One of the most common cause of SCA is an arrhythmia called ventricular fibrillation (v-fib). In v-fib, the ventricles (the heart''s lower chambers) fail to beat normally.
If immediate defibrillation is provided to a person experiencing sudden cardiac arrest chances of survival dramatically increase, compared to delayed defibrillation.
Types of defibrillators include:
ICD is recommended to people who are at risk of:
