virvendusarütmia
Virvendusarütmia, also known as atrial fibrillation (AFib), is a common type of irregular and often rapid heart rhythm. It originates in the atria, the upper two chambers of the heart. In a normal heartbeat, the atria contract in a regular, coordinated manner to push blood into the ventricles, the lower chambers. In virvendusarütmia, instead of a strong, regular contraction, the atria quiver or "fibrillate" chaotically. This disorganized electrical activity leads to an irregular and rapid heart rate.
The symptoms of virvendusarütmia can vary widely. Some individuals experience no symptoms at all, while others
Several factors can contribute to the development of virvendusarütmia. These include advanced age, high blood pressure,
Diagnosis typically involves an electrocardiogram (ECG) to record the heart's electrical activity. Treatment aims to restore
