The T wave in an electrocardiogram (EKG) is a crucial component that represents the repolarization of the ventricles of the heart. Normal characteristics of the T wave include being symmetrical and having a relatively rounded shape, without being excessively tall or pointed.

When the T wave is symmetrical, it demonstrates a balanced appearance on both sides, which is a sign of normal ventricular repolarization. Hyperacute T waves can sometimes signify conditions such as myocardial ischemia, but in the context of normal characteristics, the focus is on the T wave being smooth and gradually returning to the baseline rather than being overly sharp or steep.

Other characteristics like being flat, inverted, or pointed are not typically associated with normal T wave morphology. A flat or notched T wave may indicate an electrolyte imbalance or other cardiac issues, while pointed or peaked T waves are often associated with conditions such as hyperkalemia. Inverted T waves can indicate underlying heart disease or abnormalities, as they are not characteristic of a healthy heart.

In this context, the selection of symmetrical and hyperacute aligns well with what is expected for a normal T wave, highlighting the importance of shape and symmetry in interpreting EKG readings.
