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 […]

12 Lead ECG – Lead Placement Diagrams
I have been doing EKG's for the past thirty years. It use to be that you always lay the patient in the supine position but here lately I have been told that with the patient sitting up right will not change the EKG, is this so ?

Understanding Atropine
Hi Tony, thank you for writing. It's always a bit of a gamble to give opinion in such topics without being there, however, addressing ventilation is a must. The rate could be secondary to vagal stimulation and/or respiratory depression, but it sounds like the patient is compensating pretty well when it comes to the hemodynamic…

Understanding Atropine
Looking for an opinion. Had a pt. who was unconscious from unknown etiology, Agonal respiration = 6, SPO2 = 59, heart rate =37 sinus bradycardia, B/P = 137/80 . We ventilate the pt. approx for 2 minutes without change in status. Would you have administered atropine or continue with BVM to attempt to correct hypoxia,…

57 year old male: Chest Discomfort
I'm sorry but I don't see any flutter here. With a rate of 150 we are at the very upper limit of sinus tach. No O2 is indicated with a pulse ox of 94%, especially if you are thinking cardiac. Place in position of comfort, large bore IV, fluid bolus, ASA, nitro, capnography, complete assessment…

68 y.o. male with weakness: “Treat the monitor, not the patient?”
the bizzare complexes coupled with the fact that the patient takes a potassium sparing diuretic make me think hyperkalemia
