STEMI ischemic and reciprocal change patterns

In a cardiac emergency, pattern recognition saves lives. The ability to rapidly identify ST-elevation myocardial infarctions (STEMIs) — and recognize their reciprocal changes — is one of the most high-yield clinical skills you can master. But memorizing lead groupings, artery territories, and reciprocal zones can feel abstract… until now.This podcast brings EKGs to life inside a colorful, stadium-themed world where each ECG lead is a character in the crowd — making it dramatically easier to remember the key patterns of ischemia and their reciprocals. Whether you’re a student, clinician, or educator, this episode transforms clinical EKG interpretation into vivid, unforgettable storytelling.🧠 Characters You’ll Meet: • Inferior Peasants (II, III, aVF) — Dirty, disheveled townsfolk crowd-surfing with broken RC cars (Right Coronary Artery), holding crossed-out nitro packs to remind us: No nitro in RCA infarcts! • Royal Ladder Holders (I, aVL, V5, V6) — Crowned kings and queens dropping through trapdoors as reciprocal ST depression hits the lateral leads, each holding golden ladders labeled Left Circumflex. • Cavemen with Septal Bones (V1–V2) — Giant-nosed, primitive figures gripping a huge bone marked SEPTAL, standing just in front of… • Shirtless Musclemen (V3–V4) — Tattooed with the word Anterior, these strongmen are chained to a floating AC unit labeled Left Ventricle — representing the LAD (Widowmaker). • Posterior Posts (V7–V9) — Hydraulic pylons rising behind the wall, symbolizing posterior MI that’s often missed without reciprocal signs.🎯 Quick Reference Patterns Covered in the Episode:⸻✅ Inferior MI (II, III, aVF)• ST elevation: Inferior leads• Reciprocal depression: I, aVL (high lateral)→ “When the peasants rise, the royals fall.”✅ High Lateral MI (I, aVL)• ST elevation: High lateral leads• Reciprocal depression: III, aVF→ Works both ways: “The balcony royals rise, the peasants fall.”✅ Posterior MI (V7–V9)• ST elevation: Posterior wall (not on standard 12-lead!)• Reciprocal depression: V1–V3→ “When posterior posts rise, septal cavemen drop.”✅ Anterior MI (V2–V4)• ST elevation: Anterior leads• Possible reciprocal depression: II, III, aVF→ Sometimes: “When the chest heroes rise, peasants tremble.”✅ Low Lateral MI (V5–V6)• ST elevation: Low lateral leads• Reciprocal depression: V1–V2 (septal)→ “Kings and queens rise, cavemen fall.”⸻🔥 Bonus Insights: • Why reciprocal changes matter: They can confirm a true STEMI, suggest a larger infarct area, and sometimes reveal hidden infarctions (like posterior MIs). • LBBB & Reciprocal Thinking: LBBB distorts ST segments, but understanding the mirror logic behind “William” (LBBB) and “Marrow” (RBBB) helps clarify expected patterns. ST depression in V1–V2? May just be part of LBBB — unless it’s concordant…📌 Use this episode as your visual and verbal anchor. Once you’ve seen the peasants, the royalty, the cavemen, and the Left Vent AC unit, you’ll never look at a 12-lead the same way again.
