The District, true to reputation, is a more expensive place in which to do business--its corporate tax rate of 9.975 percent is well above Maryland's 7 percent and Virginia's 6 percent.
Home > Conditions & Treatments > Arrhythmia > Ventricular Fibrillation. Ventricular fibrillation is a condition in which the heart's electrical activity becomes disordered. When this happens, the heart's ventricles, the lower chambers that pump blood, contract in a rapid, unsynchronized way. The ventricles flutter rather than beat, causing the heart to pump little or no blood. Ventricular fibrillation is life-threatening and requires prompt treatment. Collapse and sudden cardiac death will follow in minutes unless medical help is provided immediately.
Ventricular Fibrillation. Ventricular fibrillation, or v-fib, is a common cause of out-of-hospital cardiac arrest. In this case, the heart quivers ineffectively and no blood is pumped out of the heart. On the monitor, v-fib will look like a frenetically disorganized wavy line.ine v-fib is sometimes mistaken for asystole. As the treatments for asystole and ventricular fibrillation are different, it is important to differentiate between the two. If in doubt, it is acceptable to deliver a shock.
