Ecg - simple translation needed please

Hi there

I wonder if you could explain to me in laymans terms the following extract from a recentl letter please?

" 12 lead ecg confirmed sinus rhythum with a normal PR interval and axis, There is squaring of the ST segment in leads V4-V6 and an associated repolarization abnormality in II, 111, and aVF. QTc 431 msec"

" I have looked through all her ecgs traces and there is no doubt that that they are not entirely mormal and we should document that on occasions there has been Dysrhythmia, T wave invertion, variable ST segment shift and incomplete right bundle branch block.

Many thanks in anticipation

All these findings are very nonspecific and don't mean much without any particular symptoms.  Even is you were having chest pain, etc, these findings don't represent anything concenring.

The squaring of the ST segment and the repol abnormalities are nonspecific and don't usually represent a blockage.  The QT is normal.

Dysrrhythmia may be a normal finding.  T wave inversion may be normal or may be a sign of repolarization abnormality which when present with an episode of chest pain may be abnormal.  Without any chest pain it is meaningless.  Variable ST segment changes usually are significant only in the setting of chest pain.  Incomplete RBBB may be a normal finding in you case.

So, all these are nonspecific and don't mean much.  If you are having chest pain and your risk factors are intermediate you should have a nuclear stress test.

Hi,

The symptoms I am dealing with daily are palpitations ++, shortness of breath on exertion, feeling faint/dizzy when I get up and occasionally I do have chest pain and sudden jolts to my chest at night waking me from sleep. I have fainted twice.I have had prolonged QTc in the past. I have just had a 7 days event monitor fitted and am awaiting the results, I am also due to have a Exercise Toleratence test on Monday.

Thank you for you opinion, I just wanted to understand what these findings may represent in a bit more detail, I appreciate what you have written but my smptoms are effecting my quality of life and I am no longer able to exercise and get very easily fatigued so I would be very grateful for any little clue as to what is going on here. My EP thinks I may have IST but my cardiologist has commented on theses others findings in his letter and wonders if something other than this could be going on? On talking to other members on Medhep it would appear that POTS could be a possibility, would that fit with the ecg result?

Mnay thanks
