How is pulseless V fib treated?
Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks, also referred to as defibrillation. If a patient develops ventricular fibrillation during synchronized cardioversion with a monophasic defibrillator, pulselessness should be verified.
How to get rid of atrial fibrillation once and for all?
Medications, shocking the heart back into rhythm, or even a procedure to potentially cure atrial fibrillation, called a catheter ablation, may be necessary. Certainly, with A-fib, an ounce of prevention is definitely worth a pound of cure!
What's the difference between vfib and AFIB?
AFib and VFib are both termed arrhythmias (abnormal heart rhythms). AFib is a type of arrhythmia termed supraventricular tachycardia, meaning that the problem occurs above the ventricles. For AFib, the abnormal heart rhythms are due to irregular electrical activity in the atria, mainly the right atrium.

What is the most important algorithm for resuscitation?
Ventricular fibrillation falls under the ACLS Adult Cardiac Arrest Algorithm and is the most important algorithm to know for adult resuscitation. 1 Ventricular fibrillation treatment starts with early and effective CPR with the application of oxygen and monitor/defibrillator placement. Keeping the brain, heart, ...
What is VF in cardiac arrest?
Ventricular fibrillation (VF or V-fib) is the most common initial heart rhythm in patients with out-of-hospital cardiac arrest (OHCA), and the most salvageable one . 5 In VF, the etiology of arrest is often attributed to either acute ischemia or non-ischemic arrhythmia. 8
How many joules should a defibrillator be?
If the defibrillator is biphasic, the manufacturer recommended joules should be selected (usually 120 to 200 joules). If the amount is unknown, use the maximum available and subsequent doses should be equivalent, and possibly higher. 1.
What is the most important intervention for cardiac arrest?
Irrespective of the cause of cardiac arrest, the most important interventions are early recognition and calling for help—including appropriate management of the deteriorating patient—early defibrillation, high-quality cardiopulmonary resuscitation (CPR) with minimal interruption of chest compressions, and treatment of reversible causes. 6
What are the causes of VF?
The easiest way to remember the most common causes of VF are to review the reversible “Hs and Ts” in cardiac arrest. The Hs include hypoxia, hypovolemia, hypothermia, hyper/hypokalemia, and hydrogen ions (acidosis). The Ts are tension pneumothorax, cardiac tamponade, toxins, and thrombosis (pulmonary or coronary).
What is ventricular fibrillation?
Key points about ventricular fibrillation. Ventricular fibrillation is a type of arrhythmia, or irregular heartbeat, that affects your heart’s ventricles. Ventricular fibrillation is life-threatening and requires immediate medical attention. CPR and defibrillation can restore your heart to its normal rhythm and may be life saving.
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 an implantable cardiac defibrillator?
Implantable cardiac defibrillators are devices that are implanted within the body that can shock the heart back to normal rhythm within seconds if V-fib is present. Although this device does not necessarily prevent V-fib, it can rapidly and automatically diagnose and treat this potentially fatal heart rhythm.
What is a V-fib?
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 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.
What does it mean when your heart is quivering?
The quivering means that your heart is not pumping blood out to your body. In some people, V-fib may happen several times a day. This is called an “electrical storm.”. Because sustained V-fib can lead to cardiac arrest and death, it requires immediate medical attention.
What are the vital signs of a person?
Your vital signs, such as your blood pressure and pulse. Tests of heart function, such as an electrocardiogram. Your overall health and medical history. A description of your symptoms that you, a loved one, or a bystander provides. A physical exam.
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 is the most common cause of sudden cardiac death?
Ventricular fibrillation happens when the electrical signals in your heart go haywire. This causes a ventricle to quiver (fibrillate) instead of pumping blood through your body. Without medical treatment right away, V-fib can be deadly. In fact, it’s the most common cause of sudden cardiac death.
What are the symptoms of ventricular fibrillation?
The main symptom is fainting. 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: Chest pain. Pounding or fast heartbeat.
What is an AED in medical dramas?
They’re the paddles placed on a person’s chest to shock their heart into beating the way it should. This type is called an automated external defibrillator (AED). It can help save the life of someone who’s in cardiac arrest.
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 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 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.
How to save a loved one's life?
schools. Proper training in CPR can save a loved one’s life. Consider enrolling in a CPR training course. If you’re trained in CPR and someone near you experiences a VF episode, you can deliver 30 compressions for every two rescue breaths. Continue performing CPR until emergency help arrives.
How fast does CPR work?
When someone trained in CPR delivers hard, fast compressions on your chest at a rate of 100 pushes per minute, it can help move blood through your body to vital organs. New guidelines suggest that chest compression is the most important maneuver and should be done immediately to maintain circulation.
What are the symptoms of a ventricular fibrillation?
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.
What is a T wave alternans test?
T-wave alternans testing can also be done. In this type of test, slight changes in your electrocardiogram’s T wave are monitored during gentle exercise. A T wave is one of the heart waves depicted on the electrocardiogram, which is a graphic visual representation of your heart’s electrical activity.
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 type of surgery is required to bypass a blocked artery?
More invasive surgery types, such as coronary bypass surgery, may also be required. Coronary bypass surgery involves the attachment of a healthy artery to your blocked one. This will allow blood to bypass the blocked artery and flow smoothly through the newly attached artery.
What are the symptoms of ventricular fibrillation?
These warning signs may include: Chest pain. Very fast heartbeat (tachycardia) Dizziness. Nausea.
What to do if you have a fast heartbeat?
If you see someone collapse, seek emergency medical help immediately. Follow these steps: Call 911 or your local emergency number . If the person is unconscious, check for a pulse.
What causes the ventricles to quiver uselessly instead of pumping blood?
In ventricular fibrillation, rapid, irregular electrical signals cause the ventricles to quiver uselessly instead of pumping blood. To understand how ventricular fibrillation occurs, it may be helpful to know how the heart normally beats.
How to do CPR with no pulse?
If no pulse, begin CPR to help keep blood flowing through the body until an automated external defibrillator (AED) is available . The American Heart Association recommends hands-only CPR. Push hard and fast on the person's chest — about 100 to 120 times a minute.
