Atrial fibrillation patients pulse and heart rate generally how much difference

Atrial fibrillation (AF) is an atrial fibrillation (AF) that occurs when the heart beats faster

than normal, and when the pulse rate decreases, the heart rate decreases. The atrial fibrillation is caused by the loss of normal rhythm, rapid and irregular heart rate, and the atrial contraction function weakens. It is not possible to maintain sufficient peripheral blood loss every time the heart beats, resulting in a heart rate greater than

the pulse rate.
