Talk:ST segment

Untitled
I see no "edit" ability on the article page, but the article cries out for an introductory phrase reading, "On an electrocardiogram...".

As it stands now, many people will have no idea what all these waves and letters refer to. The ECG is mentioned in very small print in the image caption, but that's it.

Is the article meant to say the period when it is repolarized, not depolarised. — Preceding unsigned comment added by Beager (talk • contribs) 08:16, 25 July 2013 (UTC)
