Help!!! Long QT syndrome :( not sure what to think

[emjeansx]

Hi there, I have been having trouble lately, as I am quite concerned that I may have LQTS... I have never experienced any fainting episodes in my life so far (im 22).. I don't have and fam history of anything of that sort either... So I'm not sure what to make of the fact that last year I had 4 ECGs that were normal and a couple of months ago I had an ECG and blood test with potassium level at 3.3 and my ECG said sinus rhythm at 72 bpm with QTc of 492!!! :( I was told go home and to not worry so much about it as I was probably born with it or my medication gave it to me, but I had been off my Effexor for a week by that point.... I've had two other ECGs since then and both had QTs of 360-362 and QTc's of 440-452 w/ HR's of 87-97. I also had a 24 HOUR holter monitor that read:

2 PVCS, 1 PAC
MIN HR 50 (6 am)
AVG HR 82
MAX HR 135 (5 pm)
LONGEST RR 1.620 sec (5 am)
0 Couplets
0 Runs
0 Beast in runs for both PAC and PVCs
PT WAS IN SINUS RHYTHM THROUGHOUT RECORDING PERIOD
HRV 50-82-135 BPM
RARE PAC/PVCs
NO LONG PAUSE OR PROFOUND BRADYCARDIA
NORMAL ST SEGMENTS
ALL WRITTEN SYMPTOMS CORRELATE WITH SINUS TACHYCARDIA

Do you think that if I did truly have LQTS it would have shown SOMETHING on the holter? :( I'm so terrified. I don't know what to do. I have a history of orthostatic hypotension from Effexor but thats about it. It was thought that I had POTS for a while and I may have a milder form of it but its much less severe than other people's then.

Thanks for all your input if any of you have the time to read it :(

You had four EKGs last year, and have had three more in the last several months.  That's a *lot* of EKGs, which are normally given due to medical indications.

But your post indicates that you are a very young woman with no family history and either few or no cardiac symptoms.

What circumstances have caused you to have so many EKGs?

Mostly to let you know some (me and I assume others) are reading, but your question is too technical for most of us.  

Your resting HR is in the upper normal, and i wonder what you blood pressure is.  If it is high normal a beta blocker (prescribed by a doctor who examines you) may provide some lowering of the HR.  I don't know what that does to the QT.

I read you have full medical advice, try to give them "facts" as accurate as possible, maybe take notes with a time/date for each entry.  You have to participate in the medical diagnosis process.
