Hi. I'm a 27 year old male, 6'4, 185 lbs, with occasional atrial fibrillation and have recently been experiencing panic attacks the last few months. I flew for the first time nice having been diagnosed with these problems. Couple of days ago and during the decent into the airport, my heart rate increased a great deal, my hands and feet went cold and began to tingle, and I felt very dizzy and out of breath. Was this just a panic attack,or something more? I know that some sufferers of arrhythmia should not fly, am I one of them? My resting heart rate is between 55-60, I'm athletic and in good shape, exercising 5-6 times a week, quite intensely. Unfortunately, I have to fly regularly for my career, this could be bad! Thank you so much for any light you could shed on this subject!
