Defibrillator

A defibrillator is a device that delivers an electric shock to the heart to help restore a normal rhythm during certain sudden cardiac events, such as cardiac arrest. When the heart's electrical signals become chaotic or too slow, a defibrillator detects this and administers a controlled shock to reset the heart’s electrical activity. This intervention can be life-saving, especially if used promptly. Modern defibrillators, including Automated External Defibrillators (AEDs), are designed to be user-friendly, guiding bystanders through the steps needed to assist someone in cardiac distress until professional medical help arrives.
