Definition Causes and symptoms Diagnosis Treatment Prognosis Prevention Resources |
Ventricular fibrillation is often associated with acute ischemic events (ischemia involves the deprivation of oxygenated blood to an area of tissue), and with chronic ischemic heart disease. It is frequently seen immediately following a heart attack. It may also develop during hypoxia, atrial fibrillation, or improper grounding of electrical devices. An extremely low level of potassium in the blood can also cause ventricular fibrillation.
The first, and usually the only, symptom of V-fib is sudden unconsciousness.
