Exploring Posterior and Septal STEMI: Posterior STEMI: Posterior STEMI often accompanies inferior or lateral infarctions and can be tricky to diagnose due to its subtle presentation on a standard 12-lead ECG. Key indicators include: - Standard 12-lead ECG: Look for ST-segment depression in the anteroseptal leads (V1-V3). - Posterior Leads (V7-V9): Confirm with ST-segment elevation in these leads. - Clinical Features: May include **hypokinesis and akinesis in the posterior segments of the left ve

📌STEMI: Your Quick-Reference Guide for Every Cath Lab Scenario! 🚨 6 Critical STEMI Types 👉🏻 Must Know 🔹 Anterior | Inferior | Right Ventricular 🔹 Posterior | Septal | Lateral 💡✅ Artery Culprits: LAD = Anterior/Septal STEMI (⚠️ High risk of LV dysfunction, septal rupture). RCA = Inferior/RV STEMI (💧 Fluids > Nitrates). LCx = Posterior/Lateral STEMI (🔍 Always check for associated mitral regurgitation). ✅ ECG Life-Savers: V1–V4 → Anterior II, III, aVF → Inferior V7–V9 → Posterior V4R → Rig
