Here is a graphic I created to help explain Sgarbossa’s criteria for identifying acute myocardial infarction (AMI) in the presence of left bundle branch block (LBBB) or paced rhythm.
In a previous article I showed this graphic which was created using PowerPoint.
Here is a similar graphic I created this morning by cropping actual ECGs that meet the criteria.
Found on the Lifenet Receiving Station (LBBB with concordant ST-depression in leads V3 and V4)
62 year old male CC: Chest pain (LBBB with ST-elevation > 0.2 the QRS complex)
58 year old female CC: Chest pain – Conclusion (meets all 3 of Sgarbossa’s criteria)
