Ventricular Fibrillation Q&A
What is ventricular fibrillation?
Ventricular fibrillation is an irregular heart rhythm (arrhythmia) that occurs when the muscles in the lower chambers of your heart (ventricles) twitch or quiver in a fast and uncontrollable way.
When these muscles fail to work properly, they can’t push blood out of your heart. That causes a sudden cardiac arrest.
What causes ventricular fibrillation?
The most frequent causes of ventricular fibrillation include:
- Heart attack
- Congenital heart disease
- Damaged heart muscle
- Heart muscle disease
- Loss of blood flow
- Electrocution accidents
- Potassium imbalances
- Aortic dissection
- Pulmonary embolism
Ventricular fibrillation can also occur after experiencing a sudden blow to the chest directly above your heart.
What are the symptoms of ventricular fibrillation?
If you have ventricular fibrillation, your heart quits working, and you stop breathing, lose consciousness, and collapse. Though it often happens suddenly and without warning, you may have symptoms before you collapse, such as:
- Chest pain
- Tachycardia (very fast heartbeat)
- Shortness of breath
Sudden cardiac arrest due to ventricular fibrillation can cause death within a few minutes.
How is ventricular fibrillation treated?
Ventricular fibrillation requires immediate cardiopulmonary resuscitation (CPR) and shocking the heart into starting again using an automated external defibrillator (AED).
If you see someone collapse, AEDs are widely available in most public places. The device determines if the heart is beating and tells you if a shock is needed.
The team at Phoenix Heart may prevent this condition by finding and treating heart disease before an arrhythmia occurs.
After surviving ventricular fibrillation, the team can lower your risk of future episodes with medications or one of the following:
Implantable cardioverter-defibrillator (ICD)
A small device implanted under your skin monitors your heart rhythm. If it detects ventricular fibrillation, it sends a shock to the heart to stop the abnormal twitching.
Your provider guides a long and narrow catheter through your blood vessels and into your heart. Then they use the catheter to administer hot or cold energy, blocking the irregular electrical signals causing ventricular fibrillation.
Coronary angioplasty and stenting
If you have a blocked artery, your provider uses a catheter to reach the blockage, push the plaque against the artery wall, and implant a stent to keep the artery open.
Coronary bypass surgery
In severe cases, you may need open heart surgery to reroute blood around the blocked artery.
