What does a heart look like in V-fib?
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. It is due to disorganized electrical activity. Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse….

How can you tell the difference between AFib and V-fib?
In AFib, the heart’s rate and rhythm will become irregular. Although serious, AFib is not typically an immediately life-threatening event. In VFib, the heart will no longer pump blood. VFib is a medical emergency that will lead to death if not treated promptly.
What is the survival rate of V-fib?
Previous studies of patients with an out-of-hospital cardiac arrest with ventricular fibrillation have reported survival rates after hospital discharge ranging from 3 to 33 percent in a variety of settings. In communities without access to early defibrillation, mortality rates exceed 90 to 95 percent.
Can V-fib go away on its own?
Ventricular tachycardia may go away on its own within 30 seconds (nonsustained V-tach ) or last more than 30 seconds (sustained V-tach or VT ).
What causes v fibrillation?
The cause of ventricular fibrillation is not always known but it can occur during certain medical conditions. V-fib most commonly occurs during an acute heart attack or shortly thereafter. When heart muscle does not get enough blood flow, it can become electrically unstable and cause dangerous heart rhythms.
Does V-fib have a pulse?
Ventricular fibrillation is always diagnosed in an emergency situation. A pulse check will reveal no pulse if sudden cardiac death occurred. Tests to diagnose and determine the cause of ventricular fibrillation include: Electrocardiogram (ECG or EKG).
What is the most common cause of ventricular fibrillation?
V-fib most commonly occurs during an acute heart attack or shortly thereafter. When heart muscle does not get enough blood flow, it can become electrically unstable and cause dangerous heart rhythms. A heart that has been damaged by a heart attack or other heart muscle damage is vulnerable to V-fib.
What two treatments may save a patient with ventricular fibrillation?
Treatment
- Cardiopulmonary resuscitation (CPR). CPR mimics the pumping motion of the heart and keeps blood flowing through the body. First call 911 or your local emergency number.
- Defibrillation. This treatment is also called cardioversion.
Which is worse a fib or V fib?
Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart’s ability to supply the body with oxygen-rich blood.
How Long Can You Live With V fib?
Survival: Overall survival to 1 month was only 1.6% for patients with non-shockable rhythms and 9.5% for patients found in VF. With increasing time to defibrillation, the survival rate fell rapidly from approximately 50% with a minimal delay to 5% at 15 min.
