The formula for exponential growth of a variable x at the (positive or negative) growth rate r, as time t goes on in discrete intervals (that is, at integer times 0, 1, 2, 3, ...), is. where x0 is the value of x at time 0.
Ventricular fibrillation is disorderly and irregular electrical activity in the heartâs ventricles. A heart affected by VFib âflutters.â These rapid beats prevent the heart from pumping adequate amounts of blood into the body. VFib is an emergency situation.
Ventricular Fibrillation. Ventricular fibrillation (VF) is a condition in which your heart beats in an abnormal rhythm. While your heart typically beats in a regular, steady pattern, VF causes your heart to beat quickly and out of rhythm. This is an emergency condition that may be brought on by a heart attack.hen VF occurs, the two ventricles (chambers) in the lower portion of your heart are not able to pump hard enough to move blood through your body. This makes your blood pressure drop quickly and keeps blood from traveling through your body. As a result, blood cannot get to your vital organs.
