I have occassionally had the odd palpitation when exercising and so mentioned it to my doctor who then sent me for an ecg and a treadmill ecg. Still awaiting the results of the treadmill test but as it was 4 weeks ago I am assuming if there was anything bad on it the hospital would have contacted my doctor before now.
However, re my standard ECG I saw a copy of the letter the hospital sent my doctor and it said heart rate was 90bpm with a QTC of 430.
I know googling is dangerous but everything I see on the web suggests that 430 is borderline prolonged as normal rates are 429 and below, although some other sources seem to think that 440 is the cutoff. Either way, 430 seems a bit too close to abnormal for comfort. Am assuming the doctors were not concerned as nothing has been said about it and the arrhymia nurse who did the test didn't say there was anything wrong at the time.
I just wondered whether a QTC of 430 alone is something to be worried about, or whether I should trust that the doctors seem to think the ecg and (hopefully) treadmill test are normal. I do a lot of exercise, mainly swimming, and worrying about Long QT is kind of taking the fun out of training!
So should I get a specilist to review things or is 430 nothing to get concerned about?
