"atrial fibrillation" is the irregular quivering action of the atria, which in turn, may cause "palpitations" (the awareness of an irregular heartbeat) and/or "tachycardia" (rapid heartbeat).
The condition of irregular quivering of the atria and rapid ventricular heartbeat is atrial fibrillation, or a-fib. While serious, a-fib is not immediately life threatening.
Atrial fibrillation is the medical term meaning the irregular, uncoordinated, ineffective twitching contraction of the walls of the atria. A related condition is ventricular fibrillation, which occurs in the lower chambers of the heart.
