🔴Which ECG lead reflects which coronary artery?✅🫀⤵️
🔹This diagram gives a clear and simple overview of how different parts of the heart, supplied by specific coronary arteries, are reflected in various ECG leads. Understanding this helps in localizing the site of myocardial infarction.
1️⃣ Right Coronary Artery (RCA) supplies the inferior part of the heart and is seen in leads II, III, and aVF. If these leads show ST elevation, it suggests an inferior wall MI.
2️⃣Left Anterior Descending (LAD) artery supplies the front of the heart, including the septum. Leads V1 to V4 correspond to this region. ST elevation here indicates an anterior or septal MI.
3️⃣ Left Circumflex (LCx) artery and its obtuse marginal branches supply the lateral wall. This is reflected in leads I, aVL, V5, and V6, where changes suggest a lateral MI.
4️⃣ Posterior Descending Artery (PDA)
supplies the back of the heart. Posterior leads V7–V9 help identify a posterior MI, often associated with ST depression in V1–V3.
5️⃣ Right Ventricular (RV) branches from RCA show up in right-sided leads like V3R and V4R. These leads are especially important in cases of inferior MI to check for RV infarction.
