What is V-Fib!!!?

Question

Please explain Ventricular fibrilation to me!! I am an EMT and have studied it but cant get it through my head....any EMT's, Paramedics, Doctors, nurses, med students., can you break it down for me more clearly??

Answer 1

VENTRICULAR FIBRILLATION.
Ventricles are made of millions of muscle fibres. Normally they work in a well co-ordinated manner, such that, all fibres are either contracting or relaxing at any given time. Hence the blood is pumped out of heart and vital organs get the supply of oxygen and nutrients. When this co-ordination is lost, there is chaos. Every fibre is doing things at its own wish and will. This doesn't pump blood out of heart. Thats why V fib is associated with no PULSE!.
Understood??? ...phew !

Answer 2

Ventricular fibrillation is a potentially fatal, uncoordinated series of very rapid, ineffective contractions of the ventricles caused by many chaotic electrical impulses.

In ventricular fibrillation, the ventricles merely quiver and do not contract in a coordinated way. No blood is pumped from the heart, so ventricular fibrillation is a form of cardiac arrest. It is fatal unless treated immediately.

The most common cause of ventricular fibrillation is inadequate blood flow to the heart muscle due to coronary artery disease, as occurs during a heart attack. Other causes include shock (very low blood pressure) (see Shock), which can result from coronary artery disease and other disorders; electrical shock; drowning; very low levels of potassium in the blood (hypokalemia); and drugs that affect electrical currents in the heart (such as sodium or potassium channel blockers

Answer 3

Ok not a doctor but was EMT. V Fib is when the hearts Electrical system fails. The heart no longer beats. Instead it flutters (kind of like your eyes) This movement is to fast and not a full squeeze, so little or no blood moves.
It's like a clap of the hand.. a loud clap to a BEAT it's a complete travel of the hands in and out. V fib would be the golf clap... a FLUTTER of the hands that is fast and little movement and little sound.

Answer 4

basically v-fib is an arrhythmia in which the heart is quivering, shaking if you will, very fast, no pulse, no perfusion. It does produce an electrical rhythm on an EKG, that looks much like a bunch of little squiggles. Imagine a scoop of jello on a plate. If you jiggle that plate the jello just keeps jiggling. That is what the heart is doing in V-Fib. The only way to reverse V-Fib is to shock the heart back into a normal rhythm. Because of the lack of perfusion, there is an increased risk of blood clots to the patient. I hope this helped.

Answer 5

Ventricular Fibrillation. It's an when the electrical activity in the heart becomes erratic. the lower part of the heart "quivers" , ineffectively pumping blood, causing cardiac death.

Good luck!

Answer 6

d fib for v fib is how I remember what the heck to do. Just remember, a person in v fib is as good as DEAD, get out the paddles. Cardiovert immediately.
