Ventricular Fibrillation
Ventricular fibrillation (VF) is a dangerous, life-threatening heart rhythm problem. This type of arrhythmia can cause the heart to stop beating abruptly (cardiac arrest) and lead to death within minutes.
Ventricular Fibrillation Definition
Definition
The ventricles are the large lower chamber of the heart. They are responsible for moving blood to the organs and tissues of the body.
Ventricular fibrillation (VF) is a severely abnormal heart rhythm (arrhythmia) that can be life-threatening.
Causes ...
Ventricular fibrillation disrupts the synchrony between the heartbeat and the pulse beat. Ventricular fibrillation is most commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. It is life threatening.
Ventricular fibrillation
The heart rate is very rapid and irregular and no mechanical contraction fo the heart can occur. The patient is pulseless and rapidly loses consciousness and stops breathing. These rhythms do not revert spontaneously.
Ventricular fibrillation: About 300,000 Americans die every year of sudden cardiac death believed to be caused by ventricular fibrillation.
Ventricular fibrillation
In ventricular fibrillation (VF) many random electrical impulses 'fire off' from different parts of the ventricles. The ventricles then fibrillate.
ventricular fibrillation - a condition in which the ventricles contract in rapid and unsynchronized rhythms and cannot pump blood into the body.
ventricular tachycardia - a condition in which the ventricles cause a very fast heartbeat.
ventricular fibrillation - occurs when the ventricles beat irregularly and too fast
bradycardia - occurs when the heart beats too slow
tachycardia - occurs when the heart beats too fast ...
Ventricular Fibrillation
V-fib occurs if disorganized electrical signals make the ventricles quiver instead of pump normally. Without the ventricles pumping blood to the body, sudden cardiac arrest and death can occur within a few minutes.

Ventricular Fibrillation
Definition
Ventricular fibrillation (VF) is serious disruption (arrhythmia) in the normal rhythm of the heart.
Ventricular fibrillation affects the lower chambers of the heart. This form of cardiac dysrhythmia poses an immediate risk of death, as the heart stops pumping blood effectively.

Ventricular fibrillation - In this arrhythmia, the ventricles quiver ineffectively, producing no real heartbeat. The result is unconsciousness, with brain damage and death within minutes. Ventricular fibrillation is a cardiac emergency.
Ventricular fibrillation can be treated, but it requires applying an electrical shock to the chest called defibrillation.
If a defibrillator is not readily available, brain death will occur in less than 10 minutes.
Ventricular fibrillation is a dangerous type of arrhythmia and the most common cause of cardiac arrest. It makes the lower chambers of the heart beat rapidly or chaotically.
Ventricular fibrillation (VF)
An electrical signal is sent from the ventricles at a very fast and erratic rate.
It may cause very low blood pressure and symptoms such as weakness, dizziness, fainting or loss of consciousness.
Ventricular fibrillation and cardiac arrest
INTRODUCTION
What is a rapid heartbeat?
Ventricular fibrillation is dangerous because it cuts off blood supply to the brain and other vital organs.
Ventricular Fibrillation (VF)
A heart rhythm disorder that originates in the ventricles. It is characterized by an abnormally rapid heart rhythm that is also highly unstable and irregular.
Ventricular fibrillation (VF) occurs in 5 to 12% of patients during the first 24 h after MI, usually within 6 h.
Recurrent ventricular fibrillation (uncoordinated contraction of the ventricles of the heart)

Definition Ventricular fibrillation is a very rapid, uncoordinated, ineffective series of contractions throughout the lower chambers of the heart. Unless stopped, these chaotic impulses are fatal.

" Occurs when the electrical impulses in the heart become rapid (ventricular tachycardia) or chaotic (ventricular fibrillation) or both. This irregular heart rhythm causes the heart to suddenly stop beating.
Ventricular fibrillation is a life threatening condition. First aid consists of cardiac compressions (regular compressions of the chest bone), ...
The electrical instability of the heart can result in ventricular fibrillation (chaotic electrical disturbances affecting the ventricles, the lower chambers of the heart).

This is called ‘ventricular fibrillation', commonly known as a cardiac arrest. It should be noted that tachycardia is normal after vigorous exercise.
Bradycardia - this is when the heart beats slowly.
The most serious aspect of VT is that it can become ventricular fibrillation.
Ventricular fibrillation (VF): This is the most serious type of fast heart rate. Your heart beats in an irregular rhythm and very fast.

However, it can lead to ventricular fibrillation, which is a fast yet irregular heart beat. With this, the heart may beat so quickly and irregularly that it actually stops pumping blood. This can lead to sudden cardiac arrest and death.
An ICD can help prevent sudden death in those who have ventricular fibrillation (VF) or ventricular tachycardia (VT).
It can lead to ventricular fibrillation which is fast and irregular. With ventricular fibrillation, the heart beats are so fast and irregular that the heart stops pumping blood. Ventricular fibrillation is a leading cause of sudden cardiac death.

You have had life-threatening bouts of ventricular tachycardia (VT) or ventricular fibrillation (VF).
Your heart is weakened, too large, and does not pump blood very well.
Sustained ventricular tachycardia (a rapid and regular heart beat) or ventricular fibrillation (a rapid, chaotic, and ineffective heart beat) occurs in approximately 2 to 3 percent of patients, usually within four days of surgery.
These include heart block, atrial fibrillation, and possibly deadly ventricular tachycardia or ventricular fibrillation.

Ventricular fibrillation, where the lower chambers quiver and the heart cannot pump any blood, leads to collapse and sudden death unless medical treatment is immediately provided.
Sudden cardiac arrest is a medical emergency that occurs when the heart abruptly stops beating because of irregular, abnormal heart rhythms (arrhythmias) called ventricular fibrillation.
Pretreatment with barakol 10 mg/kg IV reduces the incidence of aconitine-induced ventricular fibrillation and ventricular tachycardia, as well as mortality. Five μg/kg IV of tetrodotoxin has the same effect.
May be used to treat paroxysmal, nodal, and ventricular tachycardias, atrial fibrillation, atrial flutter, and ventricular fibrillation.

If enough cells do this and the rhythm becomes disturbed enough, the heart will not beat at all , but will just quiver ineffectively. This is called ventricular fibrillation.
Unless this is corrected rapidly, the person might die, he says.
A prolonged Q-T interval in the electrocardiogram in children subject to attacks of unconsciousness that result from ventricular arrhythmias including ventricular fibrillation; autosomal dominant inheritance.
Ventricular fibrillation (V-fib): An erratic, disorganized firing of impulses from the ventricles. The ventricles quiver and cannot generate an effective contraction, which results in a lack of blood being delivered to the body.
The seriousness of the infarction is dependent upon the amount of heart muscle affected, how long the area is deprived of blood, and whether it affects the natural pacemaker of the heart, setting off arrhythmias such as ventricular fibrillation.
Treatment usually is not needed unless you have several extra beats in a row and/or other problems with your heart (such as heart disease or congenital heart failure).
