EKG 101

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.

For those of you enrolled in the CRASH course, here are some resources for you:

How to perform an ECG

Electrodes to leads

Rate and Rhythm


PR Interval

QRS Interval

QT Interval

ST-segments, Q-waves and T-waves (MI’s)

      Thanks. Let me know what works and what doesn’t. I made these based on what students say they need. Thanks for the kind words.

    These are amazing! I am definitely saving this website and will review them again before and during residency as well! Glad I had an opportunity to see these.

    Nice review of reading EKGs for medical students. I especially liked the explanation of bundle branch blocks using the “William” and Marrow” memory tool.
