ekg- p/pr 136/174ms, sinus rhythm, QRS:116ms, intra-atrail conduction delay, QT/QTc: 374/409ms, slight intraventricular condution delay, P/QRS/T axis: 58/39/0 deg, slight inferior repolarization disturbance, consider ischemia, LV overload or aspecific change, 72 BPM, small negative T in aVF with negative T in III, borderline ECG.What exactly does this mean? Anything to be worrying about. Ive been told i need a stress test, could the leads been put on incorrectly? After the stress test how long for results? My work depends on the quickest responce. I work on a ship and am suppose to ship out May11th.

Hi friend,
Welcome to Health Care Magic

The question of misplacing the lead does not generally arise -
That can occur usually in chest leads (especially V-3).
The changes here are in limb leads (aVF & III)....
The limb lead can be placed anywhere in the arm or leg and it will not change the outcome / Switching the right and left side leads also is another - but the changes are easily noticeable / if in doubt, repeat it! - it takes a few minutes!.

Borderline means - the changes are not definite/ it may be normal variant is some; it may be an abnormality in some. It is an indication for further work-up.

'Conduction delays' may be actual delay of conduction in the heart nerves / or from enlargement or strain of the chambers - blood pressure for example.

ECHOcardiogram is necessary to see the heart valves (muscle (Cardiomyopathy) and heart function (Ejection fraction, wall motion abnormality).

LABORATORY work-up is routine - like blood counts, sugar, urea, electrolytes (potassium in particular), and so on.

Stress test (TMT - Treadmill exercise ECG) is done to exclude Ischemia (reduced blood flow). It takes about 20 minutes to do / the result is immediate - computer generated / but has to be verified by the doctor.

Your Internist shall suggest based on the situation.

Take care
Wishing speedy recovery
God bless
Good luck

since they only asked for a stress test is that a good thing or they just forgot to ask for lab and ECHO? What are the ways to fix any problems? I walk 10 miles aday and eat very healthy. I dont want to stress all weekend over this. Thank you for your help.

If you could walk 10 miles a day(!), - the chance of having a heart disease is practically NIL!
The changes could very well be a variant, normally seen in some...

In such instances, the first step is usually stress test -a stress ECG ( may be stress ECHO too...)
Lab and ECHO are a routine / but not on priority basis in such situations... / Probably, they are planning to do during your coming appointment...Discuss with your doctor, when you see him

All the best
