I recently started a rotation in cardiology. It has been nearly 2 years since I have worked on a heart service and I was looking for a quick refresher on EKGs. Luckily, I found a great powerpoint review on the Standford website. There are only 20 or so slides and they cover major topics such as: review of heart conduction system, EKG lead placement, determining the heart rate, and determining the QRS axis. They review both the ‘quadrant’ approach to axis determination and the ‘equiphasic’ approach. If you are going to be starting a rotation in cardiology or if you just want to refresh yourself on EKG basics, I suggest you take a look.
