Cardiac Defibrillator

A cardiac defibrillator is a medical device used to restore a normal heartbeat by delivering an electric shock to the heart. It is primarily used in emergencies when a person experiences sudden cardiac arrest or life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. There are two main types: automated external defibrillators (AEDs), which are designed for use by laypersons and provide voice prompts for proper use, and implantable cardioverter-defibrillators (ICDs), which are surgically placed in patients at risk of life-threatening heart rhythms. Defibrillators work by analyzing the heart’s rhythm and delivering a shock if necessary, effectively resetting the heart’s electrical activity. Rapid access to a defibrillator can significantly improve survival rates in cardiac emergencies.
