my 2 cents
After flying for 45 years i retired in june 2010 and had my 1st attack of paroxysmal AF in july. since then i have had 2 more attacks, the second one after drinking 4/5 scotch`s which may have triggered it, however after that i completly gave up both alcohol and caffeine, and still had another attack, i believe the mistake i made was coming off the "tambacor" since last nov i have stayed on the drug and it has not happened again (so far), i went into hospital for the last 2 and since each attack caused my heart rate to go up(about 110=140) they controlled it with "cardizem" however the attacks got progressivly longer to control 1st about 10 hours 2nd 28 3rd 40.
In the hospital a nurse said that the FAA nowadays would stop u flying, but i went into the FAA`s website and it said that you could get your med back after a series of checks. My cardioligist also said not to get "dehydrated" (drink alot of coconut water) lol.
As regards the procedure where they laser a node, a friend just had it and it worked great --but--be careful with this as if any mistake happens your career is doomed. also as someone said its expensive USD 65.000.
