Went to the cardiologist and she took one look at the ECG and said there is no sign of AFIB at all and she had written up a note for me saying I'm fine. My AME seemed to be lazy as the ECG said AFIB on the readout, and he just went with it. I also spoke with FAA today and I was cleared from Oklahoma. My heart was fine. I'm just ****ed my AME told me to be class three medical and stick to local flights.
