Ventricular fibrillation

Ventricular fibrillation

Ventricular fibrillation is also fatal unless promptly cardioverted. It is recognized on the electrocardiographic monitor as a highly disorganized rhythm with no definite P waves or QRS complexes. It can be coarse or fine depending on the amplitude of the fibrillary waves. Coarse fibrillation degenerates into fine fibrillation soon, which is more resistant to cardioversion. Management of ventricular fibrillation is discussed more in the section on cardiopulmonary resuscitation.
