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 and sudden death triggered by a blunt, non penetrating, and often innocent appearing unintentional blow to the chest without damage to the ribs, sternum, or heart (and in the absence of underlying cardiovascular disease) constitute an event know as commotio cordis, which translates from the Latin as agitation of the heart.
