Ventricular Fibrillation V Fib Rhythm

This rapid and irregular electrical activity renders the ventricles unable to contract in a synchronised manner resulting in immediate loss of cardiac output.

Ventricular fibrillation v fib rhythm. They are atrial tachycardia monofocal or multifocal atrial fibrillation atrial flutter atrioventricular nodal re entry tachycardia atrioventricular re entry. Disordered electrical activity causes the heart s lower chambers ventricles to quiver or fibrillate instead of contracting or beating normally. 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. 5 in vf the etiology of arrest is often attributed to either acute ischemia or non ischemic arrhythmia.

Ineffective erratic heartbeat essential organs lose blood supply. Ventricular fibrillation vf or v fib fatal cardiac rhythm that occurs when lower chambers of the heart ventricles lose the ability to contract and circulate blood to the body. The ventricles suddenly attempt to contract at rates of up to 500 bpm. Ventricular fibrillation vf or v fib is the most common initial heart rhythm in patients with out of hospital cardiac arrest ohca and the most salvageable one.

In a normal heart rhythm an electrical signal travels from the heart s upper chambers atria to the heart s lower chambers ventricles causing the ventricles to contract and pump blood. It involves the pumping of the lower chambers of the heart while atrial fibrillation involves the upper chambers. Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. Ventricular fibrillation vf is the the most important shockable cardiac arrest rhythm.

Ventricular tachycardia vs ventricular fibrillation arrhythmia means irregular cardiac rhythm and slow arrhythmias are called bradyarrhythmias and fast ones are called tachyarrhythmias there are various types of arrhythmias. In ventricular fibrillation rapid erratic electrical impulses occur in the ventricles. 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.

This is followed by death in the absence of treatment. Ventricular fibrillation or v fib is considered the most serious cardiac rhythm disturbance.
