HEART DEFIBRILLATION Meaning and
Definition
-
Heart defibrillation is a medical procedure aimed at restoring the normal electrical rhythm of the heart when it goes into a life-threatening irregular rhythm known as ventricular fibrillation or ventricular tachycardia. It involves the delivery of an electric shock to the heart with the purpose of resetting its electrical activity and allowing it to resume pumping blood effectively.
During ventricular fibrillation or tachycardia, the heart's electrical signals become chaotic and disorganized, preventing the chambers from contracting in a coordinated manner. This results in a lack of blood flow to vital organs, which can rapidly lead to unconsciousness, cardiac arrest, and even death if not promptly treated. Defibrillation is therefore critical in improving the chances of survival.
The procedure is typically performed using a device called a defibrillator. The machine delivers an electric shock through electrodes placed on the chest or directly onto the heart. The shock briefly interrupts all electrical activity in the heart, giving the natural pacemaker cells a chance to regain control and initiate a normal electrical rhythm.
Heart defibrillation is often administered by healthcare professionals, including paramedics, doctors, and nurses, who have been trained in the use of defibrillators. Additionally, automated external defibrillators (AEDs) are increasingly available in public spaces, such as airports or shopping centers, to enable immediate access to defibrillation in case of sudden cardiac arrest.
Prompt defibrillation is a vital component of advanced cardiac life support and significantly increases the chances of survival for individuals experiencing life-threatening cardiac rhythms.

Etymology of HEART DEFIBRILLATION
The word "defibrillation" originated from the combination of two Latin roots: "de-", meaning "undo" or "reverse", and "fibrilla", meaning "small fiber". The term "defibrillator" was coined in the early 20th century to refer to a device or technique used to restore normal heart rhythm.
The word "heart" has its roots in Old English, stemming from the Germanic word "heorte", which was derived from the Proto-Indo-European root "kerd-", meaning "heart" or "center". Over time, this term evolved into "heart" in modern English.
Therefore, the term "heart defibrillation" combines the Latin root for reversing small fibers (defibrillation) with the Old English word for the center of emotions and vital organ (heart) to describe the process of restoring normal heart rhythm using an electrical shock.
