This is an irregular heart rhythm consisting of rapid, uncoordinated, and fluttering contractions of the ventricles. The ventricles do not pump blood but quiver instead. Ventricular fibrillation can be life threatening and usually has links to heart disease. A heart attack often triggers it.
Heart arrhythmias may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms. However, sometimes it's normal for a person to have a fast or slow heart rate.
