Ventricular fibrillation (V-fib) is a life-threatening cardiac arrhythmia characterized by rapid, chaotic electrical activity in the heart's ventricles. This chaotic electrical activity prevents the heart from pumping blood effectively, leading to a lack of blood flow to the brain and other vital organs. V-fib is a medical emergency and requires immediate treatment with a defibrillator to restore normal heart rhythm.
V-fib is caused by an abnormal electrical impulse in the heart that disrupts the heart's normal electrical activity. Various factors, including coronary artery disease, heart attack, electrolyte imbalances, and certain medications, can cause this abnormal electrical impulse. V-fib can also occur in people with no known heart disease.
The most common symptom of V-fib is a sudden loss of consciousness. Other symptoms may include chest pain, shortness of breath, palpitations, lightheadedness, and dizziness. If V-fib is not treated immediately, it can lead to cardiac arrest and death.
Treatment for V-fib typically involves using a defibrillator to shock the heart back into a normal rhythm. Other treatments may include medications to restore normal heart rhythm, electrical cardioversion, and implantable cardioverter defibrillators (ICDs).
V-fib is a serious condition that requires prompt medical attention. If you experience any of the symptoms of V-fib, seek medical attention immediately.
