obgraham is on the ball.
All I would add is to ask yourself it it is a problem to YOU. If you find the ectopics upsetting and your AME confirms your license is safe then find someone who has done lots, has a good reputation and insist he does it himself!!!
But if it isnt a problem for you leave well alone. Low risk is not the same as no risk, and if the cardiologists are happy to leave it then it is unlikely there will be harm in the future. Hospitals are sadly too often places where 'just in case' procedures led to more complications than the problem in the first place.
