What is the uses of defibrillator?

A defibrillator is a medical device used to restore a normal heartbeat by delivering a controlled electric shock to the heart in cases of life-threatening cardiac arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. It is commonly used in emergency settings, including hospitals and during cardiopulmonary resuscitation (CPR) efforts. Automated external defibrillators (AEDs) are designed for layperson use, allowing bystanders to assist individuals experiencing sudden cardiac arrest. The timely use of a defibrillator can significantly increase the chances of survival.
