Clarification regarding abnormal T-wave.

Hello, I am Bablu James, 39 years old. In July, I had a blood test in which my hemoglobin (Hb) level was around 17 g/dL, so I donated one unit of blood. Yesterday, I had an ECG done voluntarily, not because it was prescribed or due to any particular medical issue. However, the ECG report mentioned “T-wave abnormality.” Could you please explain what this abnormality means and whether it could indicate a serious heart-related issue? I would also appreciate your advice on whether I need any further tests or evaluation. I have been taking Fertomid 50mg since January 2026 for Infertility treatment (IVF). So do you think this is causing the increase of my hb. I have attached a photo of the ECG report for your reference. Thank you.
