Correction: Obesity causes left axis deviation. Extremely thin individuals can cause extreme right axis deviation! Apologies for that mistake.

Ninja Nerds,

In this lecture, Professor Zach Murphy will be presenting on ECG/EKG INTERPRETATION: A Systematic Approach for 12 Lead ECG/EKGs. After this course, there will not be a 12 lead EKG you can’t read. Please refer to the index if there is specifically an area you would like to get more practice with. During this lecture we will be discussing the basics of EKGs, Rate and Rhythm, ST Elevation and Abnormalities, T Wave and Abnormalities, QRS Complex and Abnormalities, QT Interval and Abnormalities, P Wave / PR Interval and Abnormalities, and finally Cardiac Axis and Abnormalities. We hope you enjoy this lecture and be sure to check out all of our social media pages and ways to support us below!
