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!”

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.

Are all STEMI patients the same?

Entry Img

When it comes to regionalized STEMI care, we treat all STEMI patients the same. But are they the same? The answer is, "No!" Most EMS protocols include a maximum ground transport time of 30-60 when bypassing non-PCI hospitals (AHA Mission: Lifeline calls them "STEMI Referral Hospitals"). The idea is that when the "first medical contact-to-balloon" […]

Right ventricular hypertrophy vs. isolated posterior STEMI

Entry Img

A reader of the Prehospital 12-Lead ECG blog asks, “How can you tell the difference (based on ECG criteria alone) between right ventricular hypertrophy and acute isolated posterior STEMI?” Well, the good news is you don’t have to tell “based on ECG criteria alone” and I’m sure all of my regular readers know that I […]

Left anterior fascicular block (LAFB)

Entry Img

A reader by the name of Jesse contacted me and wrote: I have a question. I’m trying to learn more about fasicular and hemi blocks. I was curious if you have posted, or intend to post, any information regarding these. I understand this is all done on your free time, so no rush at all. […]

Rate Related VS. Primary ST-T Changes:
I'm not sold on true A-Fib, as there is a fusion beat/PAC visible in lead V1, additionally I think that the "U" waves are possibly atrial activity. This pt could be having a fib/ flutter pattern; but its hard to say without slowing down the rate and getting expert consultation from a cardiologist. I Would…

Rate Related VS. Primary ST-T Changes:
I think I will have to agree with Michael; I just don't see all that much evidence of WPW; typically with WPW & AF the complexes vary in width and morphology due to the combination of the accessory pathway and normal pathways which I just don't see here. The rate doesn't seem to match what…

59 year old male: chest pressure – Conclusion
I read back over the details on this case and they didn't include whether or not the patient was Left-dominant. Your hunch is probably correct!

Magnesium and Cardiac Action Potential
I have a background in biochemistry, and so am able to navigate the medical science more than someone without this background. My mom has atrial fibrillation, and so I decided to do some investigation. I am AMAZED to find out how little her primary care doctor knows about Magnesium/Potassium/Calcium concentrations as they pertain to Atrial…

Rate Related VS. Primary ST-T Changes:
He's complaining of 10/10 chest pain that coincided with palpitations with a HR of 206 that is probably A-Fib. I am guessing that if you correct his rate you will allow his myocardium to become perfused again and his chest pain will subside. I would pre-sedate him with Midazolam 2mg and electrically cardiovert starting @…
