Reddit reviews The Only EKG Book You'll Ever Need

https://www.cvphysiology.com

This website is really useful for all things cardiology. Basically a textbook and pretty in-depth but all inclusive. We used this as my school(not the school the author is from) and most lectures were based on it. Really well done for understanding I thought. Didn’t even have to really study cardio that much for step 1. There’s a lot of info there so if it’s too much you can always just use it to dig deeper into what you’re struggling with.

While not free, I thought this book was fantastic for EKG’s: https://www.amazon.com/Only-Book-Youll-Ever-Need/dp/1496377230/ref=mp_s_a_1_1?ie=UTF8&qid=1541210064&sr=8-1-spons&pi=AC_SX236_SY340_QL65&keywords=the+only+ekg+book+you%27ll+ever+need&psc=1

I still reference it regularly during rotations and learned really well from the book how to get a system down for systematically reading ekg’s and what to look for.

Hope either of these might help!

I did a majority of my self learning through the text books, and supplemented with mybrady, medic tests, and a couple of more advanced books like https://www.amazon.com/Only-Book-Youll-Ever-Need/dp/1496377230/ref=pd_lpo_sbs_14_img_0?_encoding=UTF8&psc=1&refRID=TN54Z1Z7N1PFDTFSKWFY

And for quick study I used this
