What is BFIB?
Ventricular fibrillation, or V-fib, is a dangerous problem with your heart rhythm (called an arrhythmia) that keeps your heart from pumping blood the way it should. It is a medical emergency. Your heart muscle has four main sections, called chambers. The bottom two chambers are the ventricles.
What is the most common cause of ventricular 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.
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.
What is the most common outcome of untreated VF?
VF can appear suddenly as a primary arrhythmia (from the baseline of normal sinus or another supraventricular rhythm) or, more commonly, as a “degeneration” of monomorphic or polymorphic VT. If left untreated, the typical progression is from coarse to fine VF, and then eventually to asystole (see Chapter 21).
Which is worse AFib or Vtach?
Is AFib or VFib more serious and dangerous? By far, VFib is more serious. If ventricular fibrillation isn’t treated immediately, the patient will have a “sudden death” or “cardiac arrest” and die.
How does ventricular fibrillation cause death?
Without immediate treatment, ventricular fibrillation can cause death within minutes. The condition’s rapid, erratic heartbeats cause the heart to abruptly stop pumping blood to the body.
Which is worse AFib or VFib?
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.
What VF feels like?
The most common signs of ventricular fibrillation are sudden collapse or fainting, because the muscles and brain have stopped receiving blood from the heart. About an hour before ventricular fibrillation, some people experience: dizziness. nausea.
How is sinus arrhythmia treated?
Treatment options include medications, lifestyle changes, invasive therapies, electrical devices or surgery. Antiarrhythmic drugs are medications used to convert the arrhythmia to a normal sinus rhythm or to prevent an arrhythmia.
