What is atrial fibrillation?
Atrial fibrillation is the most common heart rhythm disorder affecting humans. In a healthy heart rhythm, the stimulation takes place via the sinus node as the “clock generator” of the heart. From the sinus node, the electrical stimulus spreads throughout the heart, starting at the atria. This results in a rhythmic pumping movement of the heart muscle, in which first the atria contract and relax, then the ventricles. The blood is transported to all organs in a fluid movement.
