Atrial fibrillation is a type of cardiac arrhythmia (irregular heartbeat). Electrical impulses instruct each part of the heart to beat in sync with the other parts of the heart.
When you have Afib, the electrical signals are disorganized and cause the heart’s two upper chambers (the atria) to beat rapidly and chaotically. This prevents blood from flowing
through the heart properly.
This can lead to blood pooling in the chambers of the heart, possibly resulting in blood clots.
