Left ventricular aneurysm vs. acute anterior STEMI

Entry Img

Some of you expressed concerns about the possibility of the ECG abnormality we sometimes refer to as left ventricular aneurysm (persistent ST-elevation after previous MI).

76 year old female CC: Chest pain – The case for this being an acute anterior STEMI

Entry Img

As many of you pointed out, the history and clinical presentation isn’t exactly screaming “Acute Coronary Syndrome!”

Spot the STEMI #1

Entry Img

You have a 50/50 shot at getting this one right. Are you feeling smart… or lucky? Two 50-year-old men present complaining of chest pain x 1 hour. One patient is suffering from a very subtle acute STEMI while the other has a non-cardiac cause for his chest pain. Which patient is experiencing the subtle STEMI? […]

Computer misses it, but the medic catches it.

Entry Img

True fact: I failed out/dropped out of grad school in mathematics. But despite having little enthusiasm for topology or complex analysis, nothing drives me more nuts than people who say stuff like “I’m not good at math – just not a math person, I guess.” This attitude is not just incorrect, it’s harmful. Most mathematics […]

Anterior T wave inversions and PE.

Entry Img

Last week, I described the case of a middle-aged male with a vague history of heart failure who had been having progressive shortness of breath for 4-5 days. On the day he called 911, he had been walking a short distance when he syncoped. EMS obtained an ECG: Compared with the prior ECG, the anterior […]

Conclusion: 53 YOF with AMS: STEMI or Secondary ST-T changes?

Entry Img

This is the conclusion to the previous case: 53 YOF with AMS: STEMI or Secondary ST-T changes? This female presented to the ED with Altered Mental Status (AMS), via ambulance, as STEMI ALERT, after completing approximately 3 hours of her usual dialysis. This was the 12 lead ECG provided by EMS…   We have a […]

QRS AXIS DETERMINATION

Entry Img

During ECG interpretation, cardiac Axis, or direction of electrical impulses, may be normal (physiologic) or abnormal (pathologic), suggesting abnormal cardiac conductivity. Although every deflection obtained on the ECG will have an axis, we will focus on the ventricular axis. When we think of our cardiac monitoring lead placement, we have to understand cardiac Vectors, which is the […]

RBBB Abnormalities Missed

Entry Img

The original presentation of this case appeared as  "What's Wrong with Mr. Wilson?"… You can read the original post here. Much has been written lately about RBBB abnormalities that were missed.  Dr. Smith has recently posted two cases here, and here discussing this. First, let's review the 12 lead of a typical RBBB. When learning […]

AHA changes acceptable time to primary PCI from 90 to 120 minutes for acute STEMI

Entry Img

Thanks to Ivan Rokos, M.D. for pointing out an important change in the 2011 ACCF/AHA/SCAI Guidelines for Percutaneous Coronary Intervention. Photo credit: Code STEMI Web Series at First Responders Network For years now many have complained about the AHA's official recommendation that primary PCI for acute STEMI be accomplished within 90 minutes of first medical […]

Excessive discordance as a marker of acute STEMI in LBBB

Entry Img

Positively deflected QRS complexes can be expected to show ST-depression and inverted T-waves.
