ECG Blog #225a — ECG VIDEOS (Media Pearls)

Dear Reader: As part of my ECG Media PEARL Series, that I began January, 2021 — I have been expanding and updating ECG videos that I have made. To facilitate review — I'll be including all ECG VIDEOS on this web page (as well as in the ECG Blog post where they first appear).
  • As always — I welcome your input! For comments or questions: WRITE ME at —
