I had an EP study yesterday.... Atrial tachycardia was induced and found.... He didn't or couldn't ablate.... He said I had a problem with my artery to my heart as it did not go straight up as normal ... He showed me on the recording of the study... It had a short stump where it branched out to the right at the bottom of the stump, then went up and back over to the left... He said he needed to go into the left atrium but also that he needed to come up with a new plan.... Any ideas or similar problems?
