This is an excellent example of acute inferior wall ST elevation M.I. (STEMI) in a 78 year old woman who had been experiencing intermittent chest pain for two days. This 12-lead ECG has been formatted to simultaneously produce three rhythm strips below the 12-Lead. The rhythm strips are run simultaneously with the 12-Lead, and show 3 different leads. This feature can been invaluable when trying to decipher complex rhythms.
In this case, the patient is in normal sinus rhythm, and has classic ST segment elevation in the inferior wall leads: II, III, and aVF. There is some reciprocal ST depression in Leads I and aVL, and also in V1 and V2, suggesting injury extending up the posterior wall. ST depression is noticeable in V6 as well. This patient's RCA lesion was opened and stented, and she did well immediately post cath. We have no records past that.
