I received a diagnosis of "Sinus Rhythm, T Wave Abnormality in anterior leads, borderline abnormal for age (29) and gender (F). Abnormal ECG. Worried?

Cardiologist. These T wave abnormalities are nonspecific and it's important to compare them to any prior EKG if one is available. If none are available the findings may not necessarily be due to any cardiac pathology and may even be a normal variant in a young woman. A cardiologist is best qualified to evaluate and examine you and recommend further testing like an echocardiogram if deemed advisable.
