Etymology:
The word "defibrillator" is derived from the Latin words "defibrillare" (to remove fibrillation) and "-tor" (an agent or device that performs an action).
Meaning:
A defibrillator is a medical device that uses an electric shock to stop cardiac arrhythmias, particularly ventricular fibrillation. It works by depolarizing the heart muscle, causing it to contract in a coordinated manner and restore a normal heart rhythm.
Origin:
The concept of using an electric shock to treat heart arrhythmias originated in the early 1900s.
Defibrillators have since become essential equipment in emergency medical services, hospitals, and other healthcare settings. By delivering a controlled electric shock to the heart, defibrillators can effectively restore normal heart rhythm and save lives.
