Long,
Thanks for the post.
It appears that you are among the "worried well." The last portion of your stress tess is WNL -- Within
NormalNormal saline flush Limits. Congratulations! If we all had the same EKGs, then we would all also have the same body shape, facial features, exercise capacity, height, etc. Only clones would have the same ECG, and even then they would differ due to body position, lead placement, emotional state, etc. Since we are not all the same, doctors place qualifiers on the EKG reports, like "nonspecific ST-T wave changes", so that we can denote the fact that the ECG is not textbook normal, but is still just fine.
Rare abberancy is likewise not a cause for concern. It simply means that a rare beat conducted from the upper to the lower part of the heart in a slightly different manner than usual. Abberancy does not imply heart attack.
LVEDD and LVESV are determined by echo, thus there are no values for these since you did not have an echo.
Hope that helps. Enjoy your weekend.
