ECG Blog #100 (ECG Video-Blog-6) - Arrhythmia Management in Primary Care (Part 3)

     This is the 6th installment of my ECG Video Blog. This 40-minute video is the final part of this 3-part series on a Clinical Look at Cardiac Arrhythmias from a Primary Care Perspective. Focus in this Part 3 is on ECG diagnosis and management of the SVT Rhythms — including PSVT/AVNRT — MAT — Atrial Flutter — and Atrial Fibrillation.
NOTE: There are advantages to using a video format format. These include:
  • Ability to illustrate concepts not done full justice by the written word.
  • Greater dispersion of my content through Google & YouTube. This material is free for anyone to use.

         My goal in this 3-Part video series is to address the "art" of arrhythmia management from a primary care perspective. This includes cost-effective assessment as to whether a rhythm disturbance is present (with details on monitoring methods) — whether the arrhythmia is likely to be benign or more worrisome — and a practical approach to treatment.

      1. I would like to thank you for your great and interesting videos. I imagine they take a lot of work but I think rendering them in 720p would greatly improve our enjoyment of watching them (and ease of looking at the ECG strips).
        With great respect and appreciation for your work,
        Adrian Pop 6th year medical student

      2. @ Adi Pop - THANK YOU for your comment. YES, it takes me MANY more hours than you can imagine to develop my finished product ECG videos.

        As to your question about the resolution I use - I optimize the size of all figures (to full width of the power point slide) and often magnify key parts of the tracing. Please realize that I do reduce resolution (to standards consistent for internet recommended internet use) when making the final video - because if I did not reduce resolution - the size of these videos would be ENORMOUS. As it is, they take up more than 100 MB. That said - for me (and when I present these tracings on power point to small and large audiences) - projection is typically much clearer than it is for other speakers presenting ECG talks.

        SUGGESTION - Go to - which is a web page I developed especially for this 3-part video series on arrhythmia management that you are commenting on. You'll note under STORY after the first few bullets for download of the video - that there are additional bullets for download of a Power Point Show AND for my "Handout", including a PDF of these tracings. If you download the PDF file - and then set up this PDF file on your computer selecting FULL SCREEN MODE under VIEW ( shortcut = Command-L ) - you'll see that each slide takes up your entire computer screen with excellent resolution. For each of my videos - I also provide a Power Point Show which should give you better resolution. And of course remember that even if you just watch the video - that you can FREEZE any frame, and probably visualize at least adequate resolution to recognize the ECG points I am making.

        BOTTOM LINE: I realize that my resolution is not at the absolute highest - but it is absolutely the best possible compromise I am able to achieve given constraints of the otherwise huge file ... THANKS again for your interest! - :)
