True posterior myocardial infarction: the importance of leads V7–V9
Statistics from Altmetric.com
An ambulance crew attended a patient complaining of chest pain with a clinical picture strongly suggestive of acute myocardial infarction (AMI).
A 12-lead electrocardiogram (ECG) was obtained, which demonstrated ST segment depression of 1 mm in V2–V4 with upright T waves and hyperacute R waves in V1 and V2 (fig 1). A posterior myocardial infarction (MI) was considered and a series of posterior views was obtained to confirm the diagnosis. Leads V7 and V8 revealed ST segment elevation of 1 mm prompting removal to the cardiac catheter laboratory for expert assessment.
