Frequently Asked Questions on Defibrillator


How does a defibrillator benefit your heart?

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.

When should one use a defibrillator?

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.

Are defibrillators effective?

If immediate defibrillation is provided to a person experiencing sudden cardiac arrest chances of survival dramatically increase, compared to delayed defibrillation.

What are the types of defibrillators?

Types of defibrillators include:

  • Automated external defibrillators (AEDs)
  • Manual external defibrillators
  • Semi-automated defibrillators
  • Internal defibrillator"
Who needs an ICD (Implantable Cardioverter Defibrillator )?

ICD is recommended to people who are at risk of: 

  • ventricular arrhythmia
  • heart attack
  • sudden cardiac arrest (SCA)
  • Long QT syndrome
  • Brugada syndrome
  • A congenital heart disease or other underlying conditions for sudden cardiac arrest.
