90 year old male CC: "Possible stroke" – Conclusion

Entry Img

This is the conclusion to 90 year old male CC: "Possible stroke". You might want to go back and familiarize yourself with the details of the case. Let's take another look at the 12-lead ECG. Now with the computerized interpretive algorithm. On Facebook I had asked whether or not this ECG showed signs of ischemia. […]

63 year old male CC: Shortness of breath – Conclusion

Entry Img

This is the conclusion to 63 year old male CC: Shortness of breath. You may wish to go back and read the original post. Let's take another look at the 12-lead ECG. Now with the computerized interpretation. This ECG shows severe left ventricular hypertrophy with a "strain pattern" or secondary ST-T wave abnormality. A "strain […]

Left ventricular hypertrophy – Part II

Entry Img

I know I promised to go over the voltage criteria for left ventricular hypertrophy (LVH) but I lied! If you’re really interested you can check out the Wikipedia article HERE, the ECG Learning Center HERE, or Tom Evans’ crib sheet HERE. Personally? I think it’s a distraction. As far as STEMI recognition goes, it misses […]

Left ventricular hypertrophy – Part I

Entry Img

One of the most confusing ST-elevation mimics for paramedics is the “strain pattern” (or repolarization abnormality) occasionally found with left ventricular hypertrophy. This is important because left ventricular hypertrophy is one of the most common causes of ST segment elevation in chest pain patients. Many 12 lead ECG classes teach paramedics to recognize the voltage […]

@Gary, by all means, nitpick all you like. I agree with your assessment, and the post has been modified. Thank you for the feedback!

Not to nitpick but is this really a "slightly leftward axis"? I and AVF are both positive. I put it at about +20 degrees, not leftward.

87 YOM COMPLAINING OF CHEST DISCOMFORT AND DYSPNEA
CHF. 12-lead shows a sinus Tachycardia in the 120s with PACs, besides the anterior leads there's diffuse ST depression, the STE in the anterior leads can be explained by the LBBB, axis is good as well. I wish they posted the EtCO2 waveform so we could see but I'm assuming it's non-obstructive. The elevated EtCO2…

“Bad heartburn” – 82 y.o. female without chest pain.
Brooks, Firstly, thank you for the warm welcome to the club. Secondly, the Glasgow algorithm's only published sens/spec for AMI is 51.6%/97.6% respectively (Tuscon STEMI Database). I've not been able to find any other publications. The GE Marquette 12SL algorithm has been widely studied, but is much older, and ranges in sensitivity from 48% to…

57 Year Old Male–Chest Discomfort
Given what he was doing (paint fumes on ladder painting) I would first question if the pain is reproducable. Yes his ekg isn't normal but looks like old inferior MI. And he is hypertensive. 02 a must. Def. would give ASA. First would give morphine and see how his cp and bp are. If still…
