What is the most common symptom of ventricular fibrillation?
Collapse and loss of consciousness is the most common symptom of ventricular fibrillation. Before a ventricular fibrillation episode, you may have signs and symptoms of an abnormally fast or erratic heartbeat (arrhythmia). These warning signs may include:
How do you know if you have atrial fibrillation or AFIB?
Articles On Atrial Fibrillation. If your heart races rather than beats and the feeling lasts for a few minutes, that’s a sign you might have a condition called atrial fibrillation. You might hear it called AFib for short. Some of these symptoms, such as shortness of breath or chest pain, can mimic those of a heart attack.
What is V-fib (V-fib)?
Ventricular fibrillation (sometimes called v-fib for short) is an arrhythmia, a malfunction of the heart’s normal pumping sequence. It is the most common deadly arrhythmia.
What are the symptoms of V-fib?
Symptoms of V-fib include: 1 Near fainting or transient dizziness 2 Fainting 3 Acute shortness of breath 4 Cardiac arrest

Is there a pulse during 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.
What happens when you go into VFIB?
An arrhythmia that starts in your ventricle is called ventricular fibrillation. This occurs when the electrical signals that tell your heart muscle to pump cause your ventricles to quiver (fibrillate) instead. The quivering means that your heart is not pumping blood out to your body.
What triggers ventricular fibrillation?
The heart during ventricular fibrillation Ventricular fibrillation is caused by either a problem in the heart's electrical properties or by a disruption of the normal blood supply to the heart muscle. Sometimes, the cause of ventricular fibrillation is unknown.
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.
Which is worse AFib or V-fib?
While not as common as AFib, ventricular fibrillation is more deadly. It can cause sudden cardiac arrest or sudden cardiac death, the leading killer in the U.S.
How long does V-fib last?
Duration: The estimated disappearance rate of VF was slow. Thirty minutes after collapse approximately 40% of the patients were in VF. Survival: Overall survival to 1 month was only 1.6% for patients with non-shockable rhythms and 9.5% for patients found in VF.
Can V-fib correct itself?
Ventricular fibrillation seldom terminates spontaneously, since several re-entrant wavefronts, independent from each other, coexist, and the simultaneous extinction of all the circuits is unlikely.
What is the difference between AFib and V-fib?
Atrial fibrillation occurs in the heart's upper two chambers, also known as the atria. Ventricular fibrillation occurs in the heart's lower two chambers, known as the ventricles.
Diagnosis and Tests
Ventricular fibrillation is usually confirmed by an electrocardiogram (ECG or EKG), especially after a person has been resuscitated from cardiac arrest. This is also useful to determine the heart’s ability to function going forward.
Management and Treatment
The condition is a life-threatening medical emergency and every minute counts. The following actions can help save the life of someone who has gone into sudden cardiac arrest because of ventricular fibrillation:
Frequently Asked Questions
Atrial fibrillation is similar to ventricular fibrillation, but it’s happening in the upper chambers of the heart, called the atria. When the atria fibrillate, they beat very fast (sometimes several hundred times per minute). This can cause blood to collect in the atria and over time, this can cause the atria to stretch and enlarge.
What to do if you have a V-fib?
If you have had V-fib, or are at high risk for it, follow your healthcare provider's recommendations for taking medicine to control arrhythmia. It's also helpful to discuss other more invasive options, such as an implantable defibrillator, or surgery, to prevent V-fib. Educate your friends and family about how to respond if you collapse and stop breathing.
What is the first response to V-FIB?
CPR. The first response to V-fib may be cardiopulmonary resuscitation (CPR). This will keep your blood moving.
What is ventricular fibrillation?
Ventricular fibrillation (V-fib) is a dangerous type of arrhythmia, or irregular heartbeat. It affects your heart’s ventricles. Your heart is a muscle system that contains 4 chambers; the 2 bottom chambers are the ventricles. In a healthy heart, your blood pumps evenly in and out of these chambers. This keeps blood flowing throughout your body.
What are the complications of ventricular fibrillation?
Complications include the possibility of repeat episodes of fainting or near fainting. V-fib can be fatal.
When should I call my healthcare provider?
It is extremely important to make sure that people around you know what to do in an emergency. Someone should call 911 immediately if you experience any of the following symptoms of V-fib:
What is it called when your heart beats in and out of the heart?
This keeps blood flowing throughout your body. An arrhythmia that starts in your ventricle is called ventricular fibrillation. This occurs when the electrical signals that tell your heart muscle to pump cause your ventricles to quiver (fibrillate) instead.
What is the procedure to eliminate electrical triggers of V-FIB?
Catheter ablation. This procedure uses energy to destroy small areas of your heart affected by the irregular heartbeat. This rarely used procedure for V-fib looks to eliminate electrical triggers of V-fib.
How do you know if you have VF?
Fainting or losing consciousness are the most common symptoms of VF, earlier symptoms include: chest pain. dizziness. nausea. rapid, fluttering heartbeat. shortness of breath. These early symptoms can occur one hour or less before fainting or loss of consciousness occurs.
How Is Ventricular Fibrillation Diagnosed?
Your doctor can use testing to determine if you’re at risk of a VF episode. Examples of tests that are used for diagnosis include:
What Are the Symptoms of Ventricular Fibrillation?
When VF occurs, the two chambers in the lower portion of your heart aren’t able to pump hard enough to move blood through your body. These lower chambers are called ventricles. This makes your blood pressure drop quickly and keeps blood from traveling through your body. As a result, blood can’t get to your vital organs.
What is VF in heart?
VF often begins with ventricular tachycardia, which is a very rapid heartbeat that changes the electrical impulses in your heart. This most often occurs in people who have scar tissue from previous heart attacks or heart muscle damage due to heart conditions.
What is VF in medical terms?
Ventricular fibrillation (VF) is a condition in which your heart beats in an abnormal rhythm. Your heart should beat in a regular, steady pattern. VF causes your heart to beat quickly and out of rhythm.
What to do if you have VF?
If you’re experiencing VF symptoms, have someone nearby call 911. If you suspect someone around you is experiencing VF, call 911.
How to prevent VF?
A healthy lifestyle is vital to keeping your heart healthy and preventing VF. This means: 1 You should eat a healthy diet. 2 You should stay active, such as by walking 30 minutes per day. 3 If you smoke, start thinking about ways to help you quit. Smoking can affect your arteries’ flexibility and overall cell health. Taking steps to quit can make a dramatic difference in your heart health. 4 Maintaining a healthy weight, blood pressure, and cholesterol levels can also help to prevent cardiac issues, such as VF.
What test is used to diagnose ventricular fibrillation?
Tests to diagnose and determine the cause of ventricular fibrillation include: Electrocardiogram (ECG or EKG). This quick and painless test measures the electrical activity of your heart.
Why is ventricular fibrillation considered an emergency?
The goal of emergency treatment is to restore blood flow as quickly as possible to prevent organ and brain damage.
What is the procedure to reduce ventricular fibrillation?
Coronary angioplasty and stent placement. If your ventricular fibrillation was caused by a heart attack, this procedure may reduce your risk of future episodes of ventricular fibrillation.
Why does my heart beat abnormally?
Some abnormal heart rhythms can be triggered by emotional stress. Taking steps to ease stress and anxiety can help keep your heart healthy.
How many beats does a heart beat in a minute?
If you're having an episode of ventricular fibrillation, the ECG usually shows a heartbeat of about 300 to 400 beats a minute. Blood tests. Blood tests can be done to check for enzymes that leak into the bloodstream when the heart is damaged by a heart attack. Chest X-ray.
What happens if you have a V-FIB?
Shortness of breath. Passing out. Sudden cardiac arrest is the worst thing that can happen with V-fib. The two main signs are not responding to someone touching or speaking to you, and having severe problems breathing (gasping for air or not breathing at all).
What to do if you have a V-fib?
Step 2: Defibrillation to fix your heart rhythm. Step 3: Medication to make the rhythm stable again. Defibrillators for V-fib.
What Is Ventricular Fibrillation?
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.
What are the complications of V-FIB?
V-fib can lead to serious complications including: Injuries from CPR. Skin burns from defibrillation. Brain injury from a lack of oxygen. Injury to your heart muscle. Death. Ventricular Fibrillation Prevention. You can’t completely prevent an episode of ventricular fibrillation.
What tests are used to check for heart damage?
Tests of how well your heart works, such as an EKG. Blood tests to look for heart damage. Imaging tests such as X-rays, CT scans, MRI exams, and echocardiograms. Ventricular Fibrillation Treatment. V-fib comes on quickly and needs treatment just as fast.
Why do doctors not know what causes ventricular fibrillation?
For instance, it happens most often during or right after a heart attack. That may be because the heart’s electrical signals can become unstable when there isn’t enough blood flow.
What is the VT of a heart?
You may also have symptoms of ventricular tachycardia (VT). This is when the lower chambers of your heart beat too fast. It can lead to V-fib. Signs and symptoms of VT include:
What to do if you suspect someone is in cardiac arrest?
No normal breathing (the victim is not breathing or is only gasping) If you suspect someone is suffering from cardiac arrest, it’s vital to respond appropriately and quickly. Call 911, give CPR and use an automated external defibrillator (AED) (PDF) if one is available.
What is the best treatment for ventricular fibrillation?
Reducing your risk. If you’re at risk for ventricular fibrillation and its serious consequences, your doctor may recommend: Arrhythmia medications , which can help control rhythm disturbances. An implantable cardioverter defibrillator (ICD), which can correct abnormal heart rhythms.
What are the signs of cardiac arrest?
Signs of cardiac arrest include: Loss of responsiveness (no response to tapping on the shoulders) No normal breathing (the victim is not breathing or is only gasping) If you suspect someone is suffering ...
Is atrial fibrillation a life threatening condition?
This is not an immediate life threatening condition, though long term complications do exist
Can an AED be used to help a person who is V Fib?
The AED is almost foolproof and walks the bystander through the steps of providing a shock if the cause of death if a shock is appropriate (some people have sudden death and the abnormal rhythm is not V Fib), delivering a shock is as easy as starting a car. And a reminder to those who are afraid of making a mistake…the victim is already dead, they can’t get any worse.
How do you know if your heart beats faster?
You might feel a flutter or quiver in your chest when your heart beats. Your heart might beat faster than usual, pound, or race. The feeling often lasts for a few minutes. Sometimes your heart will skip a beat.
What Is Atrial Fibrillation (AFib)?
When you have this condition, faulty electrical signals make your heart flutter or beat too fast. This abnormal rhythm stops your heart from pumping as well as it should. Your blood flow can slow enough to pool and form clots. AFib raises your chances for a stroke and other heart complications.
When Should I Call a Doctor?
Call your doctor if your heart doesn't go back into a normal rhythm within a few minutes, or your symptoms get worse. Call 911 right away if you have these symptoms, which could be signs of a heart attack or stroke:
How long does paroxysmal fibrillation last?
Paroxysmal fibrillation last 7 days or less . Persistent AFib lasts for more than 7 days. Permanent AFib doesn't go away. If your AFib continues for many months or years, you can reach the point where you barely notice the symptoms. Sometimes, they don't go away on their own.
What does it mean when your heart beats?
If your heart races rather than beats and the feeling lasts for a few minutes, that’s a sign you might have a condition called atrial fibrillation. You might hear it called AFib for short.
What to do if you have an irregular heartbeat?
If you do have an irregular heartbeat, you can get treatments to bring it back into a normal rhythm. You may also need treatments to lower your heart rate, or you may not need anything done at all. Your doctor may also recommend medication to lower your chance of having a stroke.
Does AFIB cause a racing heartbeat?
Not everyone with AFib has a racing or pounding heartbeat. A few things can affect whether you have symptoms and how severe they are, including: Your age -- older people often don't have symptoms. What caused your AFib. How much it affects your heart's ability to pump.
