Almost always T wave abnormalities require further evidence to support clinical diagnosis, the exception is an electrolytic imbalance (potassium, etc.). The T wave abnormality alone is not diagnostic of any particular condition.  T waves will usually be abnormal in ventricular hypertrophy (enlargement), left bundle branch block (could cause arrhythmia), chronic pericarditis (inflammation of outer (sac) heart tissue) , and in electrolyte abnormality.

Sometimes there is postpartum (after pregnancy) cardiomyopathy (heart enlargement) that requires treatment and there is reverse remodeling with treatment.  An enlarged heart can cause arrhythmia as well as BBB.  There may be no identifiable problem other than an unsupported t wave, and that shouldn't be of any concern
