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.
The parts of the heart where the fibrillation occurs determine the exact conditionâs name. For example, atrial fibrillation (AFib) occurs in the heartâs upper two chambers, also known as the atria. Ventricular fibrillation (VFib) occurs in the heartâs lower two chambers, known as the ventricles. If an irregular heartbeat (arrhythmia) occurs in the atria, the word âatrialâ will precede the type of arrhythmia. If an arrhythmia occurs in the ventricles, the word âventricularâ will precede the type of arrhythmia.
