Inverted T Waves in the Myocardium

In kids under 10 years of age, you should have an inverted T wave in lead V1. As the myocardium matures, over time, you will see those T waves gradually turn upright. The next thing I'd look for, so we said T wave, just general pattern and then kind of ST segments. A lot of times you'll see T wave flattening where there's just like not much of a T wave there at all.
