I had a similar situation at Mayo Phoenix. I had two ablations there for a. fib. Six months after the second ablation, I went back into a. fib. I could not get an appointment. They had me send in my Apple Watch data that reveled a fib. One week later they set me up for an ECG which confirmed what the watch showed. I still could not get an appointment, none available. I went to Banner University Heart in Phoenix. I had PF and remain in sinus with great follow up and stellar communication.
