ECG And MI and Coronary Arteries
Site Vessel occluded ECG changes Posterior: Either RCA or Circumflex Tall R waves and T wave V1-2. ST depression V1-V3
Anterior: LAD ST elevation V1-V6
Inferior: II, III, avF Either RCA or Circumflex. May be associated AV block or bradycardia
Anterolateral Circumflex / LAD (Diagonal)
Anteroseptal LAD I, aVL, V1-V4
Criteria for diagnosing MI
Differentials of ST elevation
Early Repolarisation - may be mistaken for Anteroseptal STEMI
Inferior STEMI

Correlating ECG and Culprit vessel- there is much variation.
Arterial occlusion ECG leads affected with ST elevation, T wave inversion, Q waves Left anterior descending V1-V4 Circumflex V1 - reciprocal e.g. tall R wave instead of Q waves and ST depression rather than elevation (True posterior) Right coronary artery ST elevation, T wave changes, Q waves in II, III, aVF (inferior) Distal RCA/Side branch of Cx Lateral V5/6 changes (lateral) Proximal LAD V1-6, I, aVL anterolateral Proximal RCA II,III,avF, V5,V6 inferolateral Proximal RCA/CX II,III,aVF dominant R wave in V1 (inferoposterior) Proximal RCA/CX II,III,aVF dominant R wave in V1, V5,V6 (inferoposteriolateral) ECG References
