Most commonly, the heart rate will be unusually fast with this condition; but it is possible for the heart rate to be within accepted limits or slower and still be in atrial fibrillation. You can measure your heart rate by feeling the pulse in your wrist or neck.Atrial fibrillation is characteristically identified by a rapid, erratic pulse originating in the upper heart chambers. During atrial fibrillation, the heart beats too fast, resulting in a …In atrial fibrillation or atrial flutter, the atria do not empty completely into the ventricles with each beat. Over time, some blood inside the atria may stagnate, and blood clots may form. Pieces of the clot may break off, often shortly after atrial fibrillation converts back to normal rhythm—whether spontaneously or because of treatment.
