What does a moderately abdominal ecg result means?

You might want to read trhis article, and then go back to your doctor: https://www.healthline.com/health/abnormal-ekg

Likely typo, as it is probably abnormal and not abdominal. It is more of a generic way of saying, not a perfectly normal ecg, follow up needed. Ecg’ s are highly dependent on technique/ lead placement, many changes disappear when repeated.
