Ventricular Fibrillation V Fib Rhythm
In ventricular fibrillation rapid erratic electrical impulses occur in the ventricles.
Ventricular fibrillation v fib rhythm. Ventricular fibrillation vf is the the most important shockable cardiac arrest rhythm. They are atrial tachycardia monofocal or multifocal atrial fibrillation atrial flutter atrioventricular nodal re entry tachycardia atrioventricular re entry. The ventricles suddenly attempt to contract at rates of up to 500 bpm. This rapid and irregular electrical activity renders the ventricles unable to contract in a synchronised manner resulting in immediate loss of cardiac output.
5 in vf the etiology of arrest is often attributed to either acute ischemia or non ischemic arrhythmia. Sinoatrial node sa node natural pacemaker of the heart located at the top of the right atrium send electrical signal to av. This prohibits the heart from pumping blood causing collapse and cardiac arrest. Ventricular fibrillation v fib is the worst kind of abnormal heart rhythm and is a form of cardiac arrest.
Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. Ventricular fibrillation or v fib is considered the most serious cardiac rhythm disturbance. This is followed by death in the absence of treatment. 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.
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. 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. 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. It is due to disorganized electrical activity.
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. Ventricular fibrillation v fib or vf is an abnormal heart rhythm in which the ventricles of the heart quiver instead of pumping normally.
