The posterior wall is supplied by the posterior descending artery. The PDA branches from the right coronary artery in 80% of people (those who are right coronary dominant); therefore, occlusion of RCA can result in both an inferior STEMI and a posterior MI as well. Sometimes, it is ob...
As the posterior myocardium is not directly visualised by the standard 12-lead ECG, reciprocal changes of STEMI are sought in the anteroseptal leads V1-3. Posterior MI is suggested by the following changes in V1-3: Horizontal ST depression Tall, broad R waves (> 30ms) Upright T waves Do...
Normal variant (e.g., in neonates, or in patients with a vertical heart with an axis of 90°) Right ventricular hypertrophy (RVH) Right bundle branch block (RBBB) Left posterior fascicular block (LPFB) Anterolateral MI Right ventricular strain (e.g., pulmonary embolism, COPD, pulmonary hyp...
Importance of poste- rior chest leads in patients with suspected myocardial infarction, but nondiagnostic, routine 12-lead electrocardiogram. Am J Cardiol 1999; 83:323 - 6.Agarwal JB, Khaw K, Aurignac F, LoCurto A. Importance of posterior chest leads in patients with suspected myocardial inf...

Clinical Implication of ST Segment Depression in aVR & aVL in Patients with Acute Inferior Wall Myocardial Infarction Objectives: The aim of the study was to assess the role of ST segment depression in the limb leads aVR and aVL for the diagnosis of acute posterior wall in... R Sahi,S Jia...
Yes, Coronary arteries, the ones frequently implicated in myocardial infarctions, are the delivery arm for oxygen to myocardial cells. Right Coronary Artery Supplies: Right Atrium, Anterior Right Posterior and Papillary Muscle Wall Ventricle Posterior Aspect of Septum (90% of the population) Sinus ...
• Identify the ECG changes that occur in the presence of an acute coronary syndrome. • Begin to recognize and diagnose an acute MI. What is a 12 lead ECG? Records the electrical activity of the heart (depolarization and depolarization of the myocardium) ...
