Posterior myocardial infarction (MI) accompanies 15-20% of STEMIs, usually occurring in the context of inferior or lateral infarction. Isolated posterior MI is less common (5-10% of infarcts), and the lack of ST elevation means that the diagnosis is often missed. Posterior extension of an in...

The ECG criteria to diagnose a posterior MI — treated like a STEMI, even though no real ST segment elevation is apparent — include: ST segment depression (not elevation) in V1 to V4. Think of things backwards. These are the septal and anterior ECG leads. The MI is posterior (opp...
Analysis of Rhythm: Step 1 Regular or irregular? - Regular: 1. in most cases normal SR 2. pathologic regular rhythms: escape rhythms, SVT or VT - Irregular: 1. the most frequent reason is regular SR with SVPBs and VPBs; 2. complete irregularity of the R-R intervals: atrial ...
