EKG Interpretations

Did a stress test overseas last month. Comments: Non specific ST segment change in the inferolateral leads at peak exercise. Abnormal Resting ECG (High QRS voltage) METS:14.00 at peak exercise.

Previously, from an echo, i was found to have mild LVH (IVSD 1.3, LA dimension 4.8, EF 77%, FS 46%) with mild left atrial enlargement and mildly thickened mitral valve with mild MR. I also had mild hypertension. Currently on anti-hypertensive meds (angiotension receptor blockers). No previous episodes of heart trouble except for occasional palpitations at night. What do the comments for my stress test mean? Thank you.

What do the comments for my stress test mean?

You have a good exercise capacity.  the abnormal resting EKG confirms what you already knew -- you have a mildly thick ventricle. You have changes with your EKG during activity are not specific for anything – meaning that do not definitely indicate to blockages and could be normal for someone with LVH.  A very thoughtful history and physical really helps determine how to interpret stress test results and avoid further testing unless necessary. It is probably best to see a doctor that has access to the results and discuss them.  LVH can sometimes cause non specific EKG changes.

I hope this helps.
