V Fib Rhythm Ecg

Ventricular fibrillation vfib like atrial fibrillation also is a type of abnormal heart rhythm in which the heart rate is irregular but is usually fast due to irregular contractions of the lower chambers of the heart ventricles.

V fib rhythm ecg. Skip to main content. If it detects a rhythm that s too slow it sends an electrical signal that paces your heart as a pacemaker would. Ventricular fibrillation or v fib is considered the most serious cardiac rhythm disturbance. The lower chambers quiver and the heart can 39 t pump any blood causing cardiac arrest.

It is due to disorganized electrical activity. What causes atrial fibrillation afib and ventricular fibrillation vfib. When it occurs the coordinated contraction of the ventricles is replaced rapid chaotic electrical signals. As a result the heart cannot pump blood.

If it detects ventricular tachycardia or ventricular fibrillation it sends out low or high energy shocks to reset your heart to a normal rhythm. V fib is not one of those rhythms that you wait to see if this is really happening you need to take action right away. In this case the heart quivers ineffectively and no blood is pumped out of the heart. I hope you guys have enjoyed this quick lesson regarding v fib and feel more comfortable knowing what to do when you see this rhythm.

The two images show what ventricular fibrillation will look like on an ekg rhythm strip. 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. This is followed by death in the absence of treatment. On the monitor v fib will look like a frenetically disorganized wavy line.

Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. V fib ventricular fibrillation is an emergency that requires immediate medical attention. This rapid and irregular electrical activity renders the ventricles unable to contract in a synchronised manner resulting in immediate loss of cardiac output. The ventricles suddenly attempt to contract at rates of up to 500 bpm.

Make sure you check out all of the resources attached to this lesson. Ventricular fibrillation is treated using the left branch of the cardiac arrest algorithm. Vf can rapidly lead to heart muscle ischemia and there is a high likelihood that it will deteriorate into asystole. Ventricular fibrillation v fib or vf is an abnormal heart rhythm in which the ventricles of the heart quiver instead of pumping normally.

The icd constantly monitors your heart rhythm. Ventricular fibrillation v fib is a common cause of out of hospital cardiac arrest.
