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 is life-threatening. Ventricular fibrillation (v-fib for short) is the most serious cardiac rhythm disturbance. The lower chambers quiver and the heart can't pump any blood, causing cardiac arrest. How it works. The heart's electrical activity becomes disordered.
