There are AME's that are great for quickly getting medicals when there are no complications, but not much else. Problem is as soon as something goes wrong, like the example above with the ekg, they're useless. Either they don't care or have the time or they don't have a direct line to somebody at the FAA. My advice, choose an AME who's a pilot, not too busy with his private practice, does lots of 1st and 2nd classes, and has experience with special issuance. The smallest medical non-event in the regular world is usually a much bigger deal in the flying world. You might be super young and healthy but the stupidest thing can become a headache with medicals, especially if the doctor is not in your corner.
