Complications of Ventricular Fibrillation (VFib)

What Are the Complications of VFib?

Ventricular fibrillation (VF) is a life-threatening medical emergency. When a person experiences VF, the lower chambers of their heart quiver instead of pumping blood effectively to the body. This can lead to a lack of blood flow to vital organs, including the brain. VF may lead to cardiac arrest (sudden death) and requires emergency medical attention.

During cardiac arrest, a person may stop breathing, lose consciousness, and no longer have an effective heartbeat. This is a medical emergency. Getting help right away can improve the chance of survival.

To help respond to ventricular fibrillation and reduce the risk of serious complications, take these steps:

• Call 911 right away: If someone has symptoms such as chest pain, trouble breathing, sudden swelling in the feet or legs, nausea or vomiting, fainting, or collapse, call 911 immediately.
• Use an automated implantable cardioverter-defibrillator (AICD) if available: An AED is a portable device that can deliver an electric shock to help restore a normal heart rhythm during cardiac arrest caused by VF. Follow the device’s voice and visual instructions. Using an AED as soon as possible is one of the most important steps for improving survival.
• Start CPR: If the person is not breathing normally or is unresponsive, begin cardiopulmonary resuscitation (CPR) to help keep blood and oxygen moving until emergency responders arrive. If you are unsure what to do, the 911 dispatcher can guide you by phone.

Remember that these suggestions are general recommendations and may not be suitable for everyone. It is always important to consult with your doctor for personalized advice and guidance regarding your specific condition and treatment options.
