V fib ecg. Definitions causes risk factors ecg diagnosis and management. Ventricular fibrillation v fib or vf is an abnormal heart rhythm in which the ventricles of the heart quiver instead of pumping normally. It is due to disorganized electrical activity. Prevalence of atrial fibrillation correlates strongly with age.

Mother rotor mechanism in which a stable re entry circuit is formed the mother rotor. This is pathognomonic unique to ventricular fibrillation and must not be confused with any other arrhythmia. Ventricular fibrillation is initially found in about 10 of. The mother rotor then gives rise to propagating unstable daughter wavefronts which results in the chaotic electrical activity seen on the ecg.

Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. Ventricular fibrillation v fib or vf is a life threatening arrhythmia where the muscle fibers in the heart s ventricles d. A good starting point for learning about v fib and other types of ekg interpretation is our ekg basics training course. Atrial fibrillation is the most common pathologic tachyarrhythmia only sinus tachycardia is more common.

These features include observing p wave forms measurement of ekg intervals and segments assessment of rhythm calculating heart rate and the evaluation of other relevant wave segments. The fibrillation is maintained by re entry circuits formed by some of the wavelets. Ecg features of ventricular fibrillation. This is followed by death in the absence of treatment.

The ecg criteria to diagnose ventricular fibrillation vfib on a 12 lead ecg is discussed including a brief discussion of treatment using automated external defibrillators aed and icds. No p wave qrs complex or t wave can be seen.
