Ventricular fibrillation
by Alike Medical Team ∙ Updated on June 13, 2023
General
Ventricular fibrillation is an arrhythmia characterized by rapid disorganized heart signals from the ventricles, causing them to twitch uselessly. As a result, the heart doesn’t contract as well as it should to deliver blood to the body organs. Ventricular fibrillation is a medical emergency! Ventricular fibrillation is caused during a problem in the electrical circuit of the heart or due to lack in blood supply to the heart itself. Risk factors may include older age, coronary artery disease, different heart conditions, congenital heart disease, previous heart attack, previous episode of ventricular fibrillation, cardiomyopathy, injuries to the heart muscle, drug misuse or a severe imbalance of potassium or magnesium. Without getting treated immediately, ventricular fibrillation can kill within minutes.
