fibrillation

Fibrillation is a condition where the heart's electrical signals become disorganized, causing the heart muscle to quiver instead of contracting properly. This leads to an irregular and often rapid heartbeat, which can reduce the heart's ability to pump blood effectively. In atrial fibrillation, the upper chambers of the heart (atria) are affected, while in ventricular fibrillation, the lower chambers (ventricles) are involved. Fibrillation can increase the risk of blood clots, stroke, and other complications if not managed promptly. It's a serious condition requiring medical evaluation and treatment to restore normal heart rhythm.
