NOTE: The Easy-Link to my 65-minute ECG Video-15 on, QRST Changes is at: www.QRSTecg.com — 

• Information about this Video is on my ECG Blog #118 —
• Because of the length of this video (65 minutes) — You may prefer to view it in more than a single setting (or to refer to specific parts of the video). I have therefore made a timed CONTENTS. Fast Forward at the above YouTube LINK to focus in on the specific subject area you are looking for!
