ECG Interpretation Review #143 (ECG Guru - Dawn Altman - Dr. Stephen Smith)

     One of the reasons why I have decreased the frequency of my own ECG Blog posts — is that for the past few years I have actively been commenting on Dawn Altman’s ECG Guru site — as well as on many of the wonderful ECG posts put forth by Dr. Steven Smith on his most excellent blog site. 

For those desirous of additional sources of detailed ECG commentary — I suggest you check out:
I’ve attached below links to some of my earlier posts from both of these sites for which I’ve left detailed commentary. For anyone with a real “passion” for ECG/Arrhythmia interpretation — reading through these posts ought to keep you busy for a good while. Happy reading!
 
-------------------------------------------
NOTE (10/26/2020) — For an UPDATED version with LINKS to all of my comments on Dr. Smith's ECG Blog and on the ECG Guru site — Please LOOK for the icon in the right-hand column of any page on this web site !!!
-------------------------------------------
 
Note: Below the Figure from Dawn’s most recent Instructors’Collection ECG. I’ve added my labels in Figure-1. Detailed commentary by me supplements Dawn’s initial interpretation. Enjoy!
Figure-1: ECG from a 75yo man with new chest pain. How would you interpret this ECG? What is the “culprit” artery? Do you need the bottom ECG to tell? And, WHAT is the rhythm?
