Value of Leads V7–V9 in Diagnosing Posterior Wall Acute Myocardial Infarction and Other Causes of Tall R Waves in V1–V2

Left posterolateral chest leads (V7, V8, V9) helped distinguish the multiple causes of tall R waves in V1 and/or V2, diagnosed true posterior myocardial infarction when standard leads did not, and identified the presence or absence of posterior injury in patients with inferior infarction.
