How to read an EKG

You should not leave medical school without a basic understanding of how to read an EKG. So watch these videos then download the unlabeled EKG’s for you to read prior to class (or in class). See how you do. If there are some you have trouble with, ask me or anyone of the other Emergency Physicians in the department.

I welcome any feedback on the quality of this as a learning experience for you.
