Ventricular Fibrillation Causes Symptoms Diagnosis Treatment Prognosis Ventricular tachycardia can sometimes lead to another type of arrhythmia called ventricular fibrillation. this is when electrical signals fire off in different areas of your ventricles at the same time. it causes an extremely fast, life threatening heart rhythm. your heart then can’t beat properly, which means it pumps out little or no blood. Ventricular fibrillation, or vf, is considered the most serious abnormal heart rhythm. vf is extremely dangerous and can lead to sudden cardiac death. without treatment, the condition is fatal within minutes. disordered electrical activity causes the heart’s lower chambers (ventricles) to quiver instead of contracting (or beating) normally.
Ventricular Fibrillation American Heart Association An animation from bupa uk explaining ventricular fibrillation, a type of arrhythmia. bupa.co.uk health information directory a arrhythmia. Ventricular fibrillation is a type of irregular heart rhythm (arrhythmia). during ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner. as a result, the heart doesn't pump blood to the rest of the body. ventricular fibrillation is an emergency that requires immediate medical attention. Ventricular fibrillation (v fib or vf, for short) is the most common deadly arrhythmia. with this irregular heart rhythm, your heart’s lower chambers (ventricles) beat in an erratic way. they quiver or twitch instead of expanding and squeezing. this means they can’t pump blood as they should. A heart arrhythmia (uh rith me uh) is an irregular heartbeat. a heart arrhythmia occurs when the electrical signals that tell the heart to beat don't work properly. the heart may beat too fast or too slow. or the pattern of the heartbeat may be inconsistent. a heart arrhythmia may feel like a fluttering, pounding or racing heartbeat.
