NOTE: The Easy-Link to my 42-minute ECG Video-13 on, "Essentials of Axis/ Hemiblocks" is at: www.axisecg.com —
- Information about this Video is on my ECG Blog #116 —
- Because of the length of this video (42 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!
