Workshop on Atrial Fibrillation

Workshop on Atrial Fibrillation

Workshop on Atrial Fibrillation. Group 6. Atrial Fibrillation. The most common type of arrhythmia (irregular heartbeat) In AF, atria contract very fast and irregularly. Atria get pooled by blood. Blood not being able to go into ventricles completely.
