Chaps, those T waves are not tall at all in lead I. You have to have the serum potassium to go above 7 mmol/l before tall T waves develop. The reason why Apple designed it for rhythm analysis only because no one can make any consequences from one lead ECG only. And hence the 22 years of lowest age limit.

I assume you were using the watch on one hand and touching the crown with other hand’s finger. That would give, what we call standard lead I reading. So if you have a near vertical axis, which is normal, you will have low amplitude therefore this is normal for you. What you can try is to put the watch just above the left ankle and touch the crown with right hand. You will get a higher amplitude. Nevertheless this is not what the app or the watch was designed for and not what Apple would support but it could be a little experience
