In atrial fibrillation, the atria no longer contract regularly, but fibrillate. The heart beats irregularly and often too quickly. Some sufferers perceive this as palpitations, while others have no symptoms at all. This film shows how atrial fibrillation occurs and how it changes the heartbeat.

Atrial fibrillation is the most common cardiac arrhythmia. It can occur permanently or only temporarily. The heart beats irregularly and often too quickly. A healthy heart beats in the rhythm of its most important pacemaker: the sinus node in the right atrium. At rest, it sends 60 to 80 impulses per minute, which quickly spread to both atria. The AV node receives the electrical impulses and passes them on to the conduction system, which excites the ventricles. In atrial fibrillation, however, the impulses do not arise in the sinus node, but primarily in the left atrium. From here, the excitation then spreads quickly and in an uncontrolled manner. As a result, the atria no longer contract regularly, but instead just fibrillate. If the atrial fibrillation were to spread to the ventricles, the heart would no longer be able to beat properly. The AV node acts as a kind of protective filter, ensuring that only some of the many impulses are passed on to the ventricles. Some sufferers perceive this as palpitations, while others have no symptoms at all. Without treatment, persistent atrial fibrillation can weaken the heart and increase the risk of stroke.
