ECImagine this.
A middle-aged patient walks in, drenched in sweat, hand on chest, saying that awful sentence we all hate: “Something is really wrong.”
You grab the ECG.
No big ST elevation.
Everything looks… maybe not as dramatic
But look at the ECG properly, and once you see it, you never forget it.
Look at V2 to V5.
The ST segment is dipping down, then rising straight into a tall, sharp, rocket-shaped T wave.
Not normal.
Not “just strain.”
Not “just chest pain.”
This is De Winter.
The secret STEMI that refuses to behave like a STEMI.
Here is the truth:
When the LAD artery – the widowmaker – blocks suddenly and severely, sometimes it doesn’t give you dramatic ST elevation.
Instead, the ventricle struggles so badly that it produces this strange pattern: down-sloping ST depression that blends into a huge, straight-up T wave, like a rocket taking off.
People miss this because they’re waiting for “classic STEMI.”
But De Winter is a STEMI equivalent.
Meaning: the patient is infarcting right now.
Meaning: treat it exactly the same as anterior STEMI.
Meaning: call cardiology.
Meaning: reperfusion.
This patient needs urgent PCI or thrombolysis depending on your setting.
There is no waiting.
No serial ECGs.
No “maybe it’s nothing.”
The LAD is choking.
The muscle is dying.
So what’s the rule that stops you from ever missing this again?
If you see tall, symmetrical, rocket-shaped T waves in V2 to V5 sitting on top of ST depression that slopes upward, you don’t relax.
You assume LAD occlusion until proven otherwise.
Every. Single. Time.
Once you understand this pattern, you cannot un-see it.
And the day you recognise it may be the day you save someone’s life.

I left a tool there that will put you ahead faster and more easily.
Because medics carry a huge burden, we don’t get to make life-threatening mistakes.
This will help you stay steps ahead while everyone else is still guessing.
