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.
In the heart, a ventricle is one of two large chambers that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs. The atrium (an adjacent/upper heart chamber that is smaller than a ventricle) primes the pump. Interventricular means between the ventricles (for example the interventricular septum), while intraventricular means within one ventricle (for example an intraventricular block).
