Not all MIs disappear. Some leave evidence. Here's how to find it.
EKG 103 — Old Myocardial Infarctions
"Normal Sinus Rhythm." That's what the machine printed.
Your patient is sitting in front of you with vague new symptoms of fatigue, a history of hypertension and DM2, and new Q waves in the inferior leads — all because they had an MI they didn't even know happened.
The machine missed it. Or worse — it flagged something benign as critical and sent you chasing the wrong thing entirely.
Old myocardial infarctions don't look like the dramatic STEMI patterns you trained for. They're subtler. They hide in Q waves, and in R wave progression. This course is about learning how to listen to what the strip is actually saying.
The automated EKG interpretation at the top of every strip? It's merely a suggestion, not a diagnosis. It misses old MIs. It flags normal variants as abnormal. It has no idea what your patient's history is.
You're the clinician. This course makes sure you read it better than the machine does.
What you'll master in this course
-
The two diagnostic criteria for old MIs
The exact findings you need to identify a past infarction with confidence — so a missed diagnosis never comes from not knowing what to look for.
-
Q waves — significant vs. normal
Not every Q wave is significant. You'll learn the difference between pathological and non-diagnostic so you stop over-calling and under-calling at the same time.
-
P-mitrale
That notched P wave in lead II isn't just a quirk. It's a potential window into mitral valve disease — you'll know exactly how to spot it and what it means.
-
PVCs — identified and explained
You'll know when a PVC is benign, when it isn't, and how to stop sending patients down unnecessary workup rabbit holes.
-
How to correct the machine
EKG machines get it wrong more often than anyone admits. You'll learn to recognize when the automated interpretation is off and confidently override it with your own clinical read.

After

Why this actually sticks
Most EKG education fails for the same reason.
It gives you information in a format your brain does not hold onto. You understand it while you are looking at it — and then lose it the moment you are on your own.
That is not a motivation problem or a repetition problem. It is a teaching problem. And until that changes, you will keep running into the same wall.
That is why this is taught differently. Concepts are broken down using simple visuals, analogies, and clinical stories that make the logic so clear you do not have to fight to remember it.
That is the difference between information that fades and understanding that stays with you every time a strip lands in your hands. Once you experience that, it is very hard to go back.
Not temporarily. Not when it is obvious.
Consistently.
And when that happens, something shifts:
→ You stop forcing yourself to get through it.
→ You stop rereading the same thing hoping it will finally click.
→ You start seeing patterns without second-guessing.
→ You start understanding what the heart is actually doing instead of trying to match it to something you memorized.
→ For the first time, you feel what it is like to actually know what you are looking at.
This is for you if:
→ You do not want to miss signs of an old myocardial infarction and overlook what your patient's heart has already been through
→ You've ever deferred to the machine's interpretation instead of your own read
→ You see a PVC and refer — not because you know you should, but because you're not sure you shouldn't
→ You want to stop missing the quiet findings that only show up on a closer look
→ You're building the kind of EKG confidence that holds up under pressure
Stop deferring to the machine. Start trusting your own read.
