HEART DEFIBRILLATOR Meaning and
Definition
-
A heart defibrillator, also known as an automated external defibrillator (AED), is a portable electronic medical device designed to restore normal heart rhythm in people experiencing a sudden cardiac arrest (SCA). It is an essential tool used in the field of emergency medicine.
When a person's heart is in a life-threatening rhythm disturbance, such as ventricular fibrillation (VF) or ventricular tachycardia (VT), a heart defibrillator delivers an electric shock to the heart through external electrode pads placed on the person's chest. This shock aims to reset the heart's electrical system, allowing it to resume its regular pumping rhythm.
The heart defibrillator operates by analyzing the person's heart rhythm using built-in sensors and computer algorithms. It then determines if defibrillation is required or not. If needed, it guides the user through voice prompts and visual instructions to deliver an electric shock.
Heart defibrillators are commonly found in various public places, including airports, schools, gyms, and hospitals, as well as being carried by emergency medical personnel and first responders. Their presence in these locations is crucial for immediate access to life-saving interventions when cardiac arrest occurs. Additionally, many people are trained in CPR and AED usage to enhance the chances of survival before professional medical assistance arrives.
Overall, a heart defibrillator is a vital device that can significantly increase the probability of survival in cases of sudden cardiac arrest by providing timely defibrillation and promoting effective cardiopulmonary resuscitation (CPR) until more advanced medical assistance is available.

Etymology of HEART DEFIBRILLATOR
The word "heart defibrillator" has its etymology rooted in the combination of two terms: "heart" and "defibrillator".
1. Heart: The word "heart" originated from the Old English word "heorte", which can be traced back to the Proto-Germanic word "*hertan". This term is believed to have derived from the Proto-Indo-European root "*kerd-", meaning "heart". The word "heart" refers to the muscular organ responsible for pumping blood throughout the body.
2. Defibrillator: The term "defibrillator" is a combination of two Latin roots: "de" meaning "from" and "fibrilla" meaning "small fibers". Thus, "defibrillator" signifies a device used to stop or correct fibrillation, a chaotic and irregular heartbeat.
