V Fib Ecg Strip

Ventricular tachycardia a sequence of three pvcs in a row is ventricular tachycardia.

V fib ecg strip. Atrial fibrillation afib and ventricular fibrillation vfib are both a type of abnormal heart rhythm arrhythmia. Bmc medical genetics 15 2014. It is due to disorganized electrical activity. The rate will be 120 200 bpm.

Ecg showing ventricular tachycardia degenerating into ventricular fibrillation. Av block and st elevation. When the ventricles handle the pacemaking role they can be observed on ekg tracings. A good starting point for learning about v fib and other types of ekg interpretation is our ekg basics training course.

Ventricular fibrillation is always pulseless and must be confirmed by ekg or defibrillator monitor. Ventricular fibrillation is treated according to the resuscitation algorithm. The course provides training on the key features of an ekg tracing. 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.

Second degree av block type i. The fibrillation is maintained by re entry circuits formed by some of the wavelets. Symptoms of both afib and vfib are shortness of breath dizziness nausea and chest pain. Treatment of ventricular fibrillation.

The mother rotor then gives rise to propagating unstable daughter wavefronts which results in the chaotic electrical activity seen on the ecg. Cardiac arrest and sudden cardiac death. By bagnall et al. 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.

Mother rotor mechanism in which a stable re entry circuit is formed the mother rotor. Defibrillation is the treatment of choice and should occur as soon as possible. The video below shows an example of what ventricular fibrillation will look like when you see it on the defibrillator monitor. Ventricular fibrillation is an emergency condition requiring immediate action.

Ventricular fibrillation v fib or vf is an abnormal heart rhythm in which the ventricles of the heart quiver instead of pumping normally. 12 lead and rhythm strip. Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse.
