A member asked:

I have atrial fibrillation but the blood work and ecg are normal. how is that?

A doctor has provided 1 answer

Fleeting AF: Many people are not in atrial fibrillation continuously but, rather, on and off. An ECG is a 12 second strip - you may have been in an "off" period (in normal rhythm) during the ECG recording. Blood work is usually not affected in atrial fibrillation.
