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.
Auricular fibrillation is the same as atrial fibrillation. It is a heart arrhythmia- where the heart beat does not beat at a normal pace or rate. Atrial arrhythmia is diagnosed as rapid and random contractions of areas inside the atrium of the heart, which cause totally irregular and often very rapid, ventricular heart rate.
