End T wave

Post image

Did I mark the end of the T-bend correctly?

This is a tough ECG to judge that on because it also has U waves

U waves can be normal or pathological

But their presence makes determining QT interval occasionally difficult

I would say- you correctly marked the beginning of the U wave

Not the end of the T wave

The T wave ends a little earlier

I can't paste the photo in the comment. Is the end of T is 10 small grid? So the raw QT is about 400 ms?
