T Wave Size Can Predict STEMI Before It Happens

Uncategorized Jan 24, 2022

"T waves are the key to life."

Have you ever heard someone say that? 💕

I think they are the most valuable wave we have to tell us about ischemia in the heart.

In order to know what abnormal looks like, we have to have a firm hold on what normal looks like.

So, here are some key tips to know about the T Wave:

🔥 T waves should be upright in all the leads, except for AVR and V1.

🔥 If they were inverted anywhere not in those leads, you have to worry about ischemia.

🔥 "Hyper acute T waves" are T waves that are too big in relation to their QRS complex. (This means early ischemia and STEMI is probably coming)

Can you see the power in this? Detecting early ischemia BEFORE the patient has a STEMI?

This will often show up on the ECG as "non -specific ST T wave changes". So, when it says this really scrutinize you T waves to see if they are "proportianate" to their QRS. If they appear too large they are most likely "hyperacute".
