Ventricular Fibrillation
Medical Questions » Ventricular Fibrillation
| Name: Ventricular Fibrillation |
| Also known as: VF |
| Extremely rapid vibration of heart muscle in the ventricles (larger heart chambers) that prevents any blood from being pumped out of the heart. A slower, but still very rapid, heart contraction rate that allows a small amount of blood flow, is ventricular flutter. |
Causes of Ventricular Fibrillation
Heart attack and electrocution most common causes. |
Symptoms of Ventricular Fibrillation
Sudden collapse, coma and death within minutes if not adequately treated. |
Tests for Ventricular Fibrillation
Diagnosed by ECG (electrocardiograph). |
Treatment for Ventricular Fibrillation
Cardio-pulmonary resuscitation (CPR heart massage and mouth to mouth breathing) may save some patients long enough for specific treatment to be given. Electrical shock, to heart (cardioversion) applied immediately after
patient collapses and repeated until normal rhythm occurs, followed by injections into a vein of medications to prevent further heart beat irregularities.
|
Complications of Ventricular Fibrillation of its treatment
None. |
Likely Outcome of Ventricular Fibrillation
If VF occurs in a hospital intensive care ward, a significant percentage of patients can be saved. In the community, death usually occurs before effective treatment can be given. |
