I am 37, female, 5 9, 150 lbs. A recent ECG says NSR, ST& T wave abnormality, consider inferior ischemia . I have never had an ECG before. I am healthy and take no meds. I have no family history of heart disease. Could this be a normal reading for me? I had a normal Echo as well. Could this be from an electrolyte imbalance? My doc says it is probably ok, but I m still worried.
