Types of Heart Defibrillators

Defibrillators are used to help the heart function again in an emergency. They are used by hospitals and paramedics but can also be found in public areas. Types of defibrillators include manual external, automated external and implantable.

  1. Function

    • A heart defibrillator is a device that administers an electrical shock to the heart in an attempt to regain a normal sinus rhythm.

    Manual External Defibrillators

    • Manual external defibrillators can have electrocardiogram readers to show the paramedic how much of a charge to use. These are used by trained medical professionals and can be found in ambulances and at some hospitals.

    Automated External Defibrillators

    • Automated external defibrillators are computerized and can automatically monitor the heart and send an appropriate electric shock. It's the most advanced type of defibrillator available and requires little training to use.

    Internal Cardioverter Defibrillators

    • Internal or implantable cardioverter defibrillators are similar to pacemakers. The device has a pulse generator and constantly monitors the heart.

    Training

    • Although calling 911 is the first step, being able to properly use an automatic external defibrillator can increase the survival rate of a victim by 70 percent. The American Heart Association offers CPR and defibrillator training. Call (877) AHA-4CPR (242-4277) to find a local training center, or use the online resource link to find a class.
