@gregkogan The definitive assessment is done with a 12-lead ECG which, if you do have flutter, will be revealed on the graphic display as literally a sawtooth pattern between the other waves. As for whether the patient is a good candidate for an ablation, the electrophysiologist would probably (I'm not one, nor do I have any medical training) want to be assured that you have no obvious ischemia from heart disease that needs correction first, or that you have one or more valves that need repair or rehab....that kind of thing. You would have to demonstrate a soundness and all-round health that would make his/her efforts reasonable to perform, especially since all procedures that require entry to the body offer some risk. He doesn't want to make you worse off!
