Ventricular Fibrillation or V-Fib is a type of arrhythmia of the ventricles (lower chambers) of the heart. The chambers flutter uselessly instead of in a coordinated way. It is a medical emergency as the cardiac output of the heart (amount of blood pumped per minute) falls to a level that is unable to sustain adequate tissue metabolic demands on onset of V-Fib due to the uncoordinated contraction of heart muscle cells.
Ventricular fibrillation is one of the few shockable arrythmias, with the aim of a defibrillator being to deliver an electric shock in order to depolarise all the heart muscle simulataneously, in the hopes of a coordinated electrical signal originating from the sinus node.

Identification of Ventricular fibrillation?
Ventricular fibrillation is the most serious cardiac arrhythmia and it means simultaneous haphazard electrical activity of the Heart and it occurs in death. If the patient has collapsed with no pulse and the monitor shows a flat wave, then its Ventricular fibrillation.
Which would produce the most life-threatening condition atrial flutter ventricular flutter atrial fibrillation or ventricular fibrillation?
Ventricular fibrillation, since this pumps blood to the rest of the body.
Which form of cardiac arrhythmia is fatal unless reversed?
Ventricular Fibrillation
How many people die from ventricular fibrillation?
Ventricular fibrillation is a life-threatening arrhythmia that can lead to sudden cardiac arrest. Each year, it is estimated that thousands of people die from ventricular fibrillation, especially if immediate medical intervention such as defibrillation is not provided. Early recognition and treatment are crucial in improving outcomes for individuals affected by ventricular fibrillation.
What are the major types of arrhythmia?
Atrial Fibrillation, Ventricular tachycardia, Ventricular fibrillation, Supraventricular tachycardia
How is ventricular fibrillation diagnosed?
When an individual suddenly collapses, the possibility of ventricular fibrillation should be considered immediately.
What cardiac arrhythmia is fatal unless reversed?
Cardiac arrhythmia is usually fatal unless reversed by electric defibrillation. Cardiac arrhythmia is also sometimes referred to as ventricular fibrillation.
How can ventricular fibrillation be prevented?
A healthy lifestyle to reduce the risk of heart diseases which lead to ventricular fibrillation is the best prevention.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
Can Afrin cause ventricular fibrillation?
yes
Is there a pulse rate in ventricular fibrillation?
ofcourse.
What is V-fibrillation?
Ventricular fibrillation is a rapid, irregular and uncoordinated contraction of the cardiac muscles.
