NOTE: To facilitate viewing — I have made up a Timed CONTENTS with LINKS (!) — which allows you to instantly Fast Forward on YouTube if you want to focus on a specific area (GO TO - http://ecg-interpretation.blogspot.co...). This 17-minute ECG Video (my 2nd) reviews a practical approach for diagnosing RBBB, LBBB and IVCD — which can be applied in seconds. The concept is reinforced by practice tracings. NOTE: Links to my ECG Videos (including a folder with Power Point Shows of these videos) — as well as info on my other ECG Resources can be found at — www.videoecg.com — Your Questions and Feedback are welcome!
