Defibrillator – Rescue Life 9

Defibrillator is a device that provides an electric shock to your heart to allow it to get out of a potentially fatal abnormal heart rhythm, or arrhythmia, — ventricular tachycardia (with no pulse) or ventricular fibrillation — and back to a normal rhythm. Both of these arrhythmias happen in your heart’s ventricles or lower chambers.
