Graduating MS4 here, would appreciate if anyone can recommend best resources/books to learn ECG beyond basics. I think I have the basics down but I'm nowhere near proficient or confident. TIA.
Will echo may of the resources mentioned in the responses. Everyone's learning style is different. There's no one resource that does it all for EM and EKG's, but fortunately there are a lot out there. I would avoid Dubin's- it's totally inadequate for residency.
Having taught EKG's to residents in our program for many years, some
other "tips"/thoughts:
1. You have to be as good as/better than the cardiologists at reading EKG's. Not necessarily some of the esoteric minutiae, but you'll need to know stone cold everything about ACS, arrhythmias, electrolyte problems, drug toxicities, etc.- stuff we see every day in the ED. There are many things Cards doesn't know about but EM does. You have to advocate for your patients and being a great EKG interpreter is one way to win the battle. (At least by the time you graduate, not starting out as an intern).
2. Make sure to review/read the EKGs on
ALL the patients you take care of. Not just in the ED, but in the ICUs/other rotations as well. Don't just depend on the computer or "official" interpretations- sometimes they're wrong. Review their old ones and compare them. Look at other interesting EKGs in the ED if possible, you'll learn a lot from them. Review the EKG's with your attending as well. They need to help teach you about them- EKG interpretation is not a totally self-taught discipline.
3. Although pattern recognition is important, you also have to
understand the physiology behind the EKG changes. Why does a LBBB look the way it does? What happens in the conduction system? Not every patient reads the book, and everyone's EKG looks a little different for a particular abnormality. If you don't know why they look that way, when something looks a little different, you'll miss it.
4.
Develop a DDx for EKG abnormalities- i.e., what causes STE, ST depression, T wave inversion, hyperacute T waves, QRS widening, prolonged QT, etc. Most patients whose EKG's show STE are NOT having a STEMI- they have something else. If you don't know the DDx for STE- you won't figure it out. There are lots of causes for the different EKG changes and you need to know them. Similarly for the different diseases causing abnormal EKG's- who gets AFib, who gets VT, who develops complete heart block.
Just a few random thoughts. EKG's are a blast- knowing them well takes time but you can be really good at it.
