What is Ventricular Fibrillation?
Ventricular fibrillation or VF is a brutally atypical health rhythm or arrhythmia that may be lethal.
The heart propels blood to the brain, lungs as well as other organs. Interference of the heartbeat for only several seconds may cause fainting or syncope, or to cardiac arrest.
Fibrillation is an unrestrained quivering or twitching of fibers muscle (fibrils). Once it occurs in the lower compartments of the heart, it is well-known as ventricular fibrillation. During VF, blood is not taken from the heart and therefore abrupt cardiac death is the outcome.
The more common reason of Ventricular Fibrillation or VF is known as a classic heart attack. But, VF may happen when the heart does not get the amount of oxygen it needs or if an individual has other heart problems.
Ventricular Fibrillation Symptoms
An individual who has a VF attack will collapse suddenly or become unconscious, since the muscles and the brain have stopped receiving blood from the heart. The following symptoms may happen within 1 hour before any collapse:
- Dizziness
- Chest Pain
- Rapid heart beat
- Nausea
- Shortness of breath
Causes of Ventricular Fibrillation
Conditions that may cause a VF include the following:
- Heart injury or electrocution accidents
- Congenital heart disease
- Heart muscle diseases, including cardiomyopathies
- Heart attack
- Ischemia – absence of oxygen getting to the heart muscle due to constricted coronary arteries or shock
- Surgery of the heart
- Cardiac death that is sudden – “commotio cordis” – classically seen in athletes after a distress or injury over the surface of the heart
Most individuals with VF have no prior history of disorders of the heart. But, the majority have factors for risk of cardiovascular disease, such as blood pressure that is high, smoking and diabetes.
Ventricular Fibrillation Treatment
Ventricular Fibrillation is considered an emergency medically and needs to be treated ASAP to save the individual’s life.
If an individual has a VF episode, breakdowns at home or come to be unconscious, call the local emergency number – such as 911.

While awaiting help, put the individual’s neck and head to line up with the remainder of the body to aid in making easier to breathe. Start CPR with mouth-to-mouth breathing again if needed along with compressions of the chest. Continue this until the individual is alert again or until help arrives.
The team from emergency will quite speedily examine the individual while continuing CPR. The individual will then be rushed to the hospital.
Ventricular Fibrillation is managed by the delivering of a rapid electric shock thru the chest by using a device known as an external defibrillator. This electrical shock can instantaneously regenerate the heartbeat to a rhythm that is normal.
Drugs will usually be given to regulate the heartbeat and the heart functions. Individuals with heart muscle damage may need other procedures, including a heart transplant.
The cardiologist will search for probable reasons for the VF.
An implantable device referred to as “cardioverter defibrillator” or ICD might be suggested for those who endured a VF attack and is at greatest risk for ones in the future. The ICD may help stop sudden cardiac death.
Modern hypothermia therapy might be also used on those individuals who continue in a coma after treatment. This comprises maintaining the individual somewhat below the normal body temperature for a few hours. Such management has been proven to increase positive outcomes and reduce death.
