Hi. Can anyone give me some advice? I am 36 and have been diagnosed with atrial arrythmias (AF, atypical atrial flutter and atrial tachycardia). I have had an EP study done and an ablation which was not successful. I have tried 3 different antiarrythmics but had to come off them as disopyramide gave me prolonged QT and apparently it was very long and potentially very dangerous. (It was caught by a chance ECG). I am now petrified that i am predisposed to long QT. Any ECGs i have had since coming off the medication have been normal but i have this awful fear that something has been missed in ky diagnosis. I am under the care of an EP who has seen a lot of my ECGs but i keep worrying. I never faint but sometimes get presyncope. I tolerate exercise fairly well but have not exercised in 2 weeks as i have had more frequent AF episodes. I have episodes of fast AF for between 5 and 7 hours a day. Any advice greatly welcomed as i am worried sick. Thank you.
