12-Lead EKG Made Simple for SRNAs & CRNAs | Lead II, V5, Axis & Ischemia
12-lead EKG interpretation does NOT have to be overwhelming. ⚡️ In this episode of My Favorite Learners, we break down EKG/ECG monitoring specifically for SRNAs, CRNAs, anesthesia providers, ICU nurses, and anesthesia learners—with simple analogies and clinically relevant pearls you can actually remember. We start with one of the most confusing concepts: What is the difference between an ECG lead and an electrode?From there, we build a practical understanding of 3-lead, 5-lead, and 12-lead ECG monitoring and why different leads give us different electrical views of the heart. In this episode, we cover: ECG vs EKG terminology ⚡ Electrodes vs leads 3-lead vs 5-lead vs 12-lead ECG monitoring ⚡ Why anesthesia providers commonly monitor Lead II Why V5 is valuable for perioperative ischemia surveillance ⚡ V1 vs V5 and why chest-electrode placement matters Correct V1–V6 electrode placement ⚡ Limb leads vs precordial leads Inferior, septal, anterior, and lateral ECG leads ⚡ A simple way to understand cardiac axis Left axis deviation vs right axis deviation ⚡ Left bundle branch block vs right bundle branch block Contiguous leads and myocardial ischemia/infarction ⚡ ST-segment changes during anesthesia Myocardial oxygen supply vs demand ⚡ High-yield ECG pearls for SRNAs and nurse anesthesia boards One of the biggest takeaways: Lead II and V5 aren't valuable for the same reason. Lead II gives us excellent atrial activity and rhythm information, while V5 provides valuable surveillance for ischemic ST-segment changes. Together, they give anesthesia providers two very different—and clinically important—views of what's happening with the heart. Instead of memorizing random ECG patterns, we're focusing on understanding where each lead is looking, what it's seeing, and why that matters for your anesthetic. My Favorite Learners is a pharmacology and anesthesia education podcast designed to make difficult concepts easier to understand for SRNAs, CRNAs, nurses, and anesthesia learners.
