OMG....I have never heard anyone explain the biophysical basis for ST depression and elevation so clearly and simply! Some of us learn better by learning the mechanism of things, but that not how things are taught generally in medical education, where instead it’s often “this is what you beed to know. Dont worry about why, unless you become an electrophysiologist.” Thank you!

When I tell you my mind is blown right now. I was never taught it this way and assumed it was just elevated because of something happening during repolarization. Until today when I decided to understand what is happening in the heart and ecg during elevation and depression. Thank you!!!!!!!

in a nutshell >> its the shift of isoelectric point, either high(in ST depression) or low (in ST elevation) makes it appear as ST elevation/Depression. ST elevation- subendocardial ischemia ST depression- transmural ischemia/infarct thank you man, thats pretty simple, lots of love...❤

Sir, if electrical activity is going on before QRS complex so, why is iso electric line is straight? Electrodes are sensing the vectors(thats why iso electric line is elevating or depressing) but as electrical activity is going on why there is no any deflection why the iso electric line is straight?

Amazing! I have a question. Why doesn’t the P wave appear far lower than isoelectric line if the sub endocardia ischemia is raising the line? Why does the P wave start on the same line as the raised isoelectric line? Shouldn’t it be in line with the ST depression as it isn’t being affected by the ischemia?

I didn’t quite get why would a resting membrane potential of -50 lead to the fast acting sodium channels not opening up (they were supposed to open up at above -70 so they should be open). Also didn’t understand why would the repolarization happen earlier.

Thank you. I’m a nurse. Not cardiac- HH wound ostomy care. Cardiology beyond basics is French to me. Thanks for the clear explaination of all I forgot since nursing school! I was dx today w ST depressions symptomatic but nothing but ST depressions 1.5mm on stressEKG during nuclear med test. Other findings normal. If family hx of widow maker (my dad) mom CHF, brother stents at 35. I’m 58 cardiologist gave me the choice to take meds and watch… wait and see if it resolved or angiogram- came to the hospital yesterday morning w chest pain and troponin was .97. An hour later .96 then last one .58 CT at that time showed mild pericarditis and effusion- got steroids IV then prednisone 30mg tabs daily- at stress test fluid and inflammation was already not apparent echo and nuclear stress WNL Except the ST depressions- I’m opting for the angiogram and feel good w that after watching your video on it. Thank you. I don’t need to be a ticking time bomb and wait and watch on meds that have side effects (already ill w/ Crohn’s). I’d rather find out what’s causing it and move on. Hopefully w no meds no blockage but I don’t see if there is no blockage how it won’t lead to one eventually w ischemia already.

Man, that was informative. I like the fact that you describe it in a way I need it: from an engineering perspective. I now understand, in part, what I am facing. I now would like to know which electrode detected the ischemia (is that the right word?). It sounds like the depression event if not treated will eventually become a elevation event which, according to your diagram, is a more problematic situation. BTW, I get electrodes all over my chest but none on my back. Why?
@elisearmer8306

What does it mean when it polarizes *slightly* then immediately depolarizes, then immediately repolarizes - two sort repolarization/depolarizations per heart-beat cycle with *each* of them being very slight.
@tinkumon6286

St depression makes sense but in ur explanation for st elevation, how does the change in direction of depolarisation change the resting potential below 0 ? Depolarisation goes away from electrode means only the wave gets inverted how does it lower the resting potential ?What causes the qrs to go below normal? What causes change in magnitude apart from the direction?

For that you have to understand the different leads. Leads I/avL/V5/V6 are for lateral part of the heart which represents the left circumflex artery issues. Leads II/III/aVF are for inferior part of the heart, which is supplied by the right coronary artery. V1-V4 leads are supplied by the Left anterior descending artery, for the anteroseptal part of the heart

Actually the entire picture is not presented in this video. In ischaemic state the Na-K pump devoid of ATP stops working. This causes the build up of positive charge inside the sarcoplasm. Leakage of K+ is also there. Consequently there is a partly depolarised state in these myocytes.
