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 an immediately life-threatening arrhythmia in which the heart's. electrical activity and associated contraction become disordered and ineffective. It is. characterized by rapid, irregular activation of the ventricles and thereby prevents an effective. mechanical contraction.
