Do you mean positive deflection or positive charge? Basically your heart is stuck in a contracting state. Like a cramp, it’s struggling to completely depolarize due to myocardial ischemia in the coronary artery. The vector is deflecting positive as it passes through purkinje fibers but on halt before it can’t completely contract the entire chamber. Action potential is forced to drop below J point or above Jpoint prematurely.
New to the stress lab. So much to learn but this is a great and simply put explanation.
Thank you so much, you have cleared my doubt on ST80 & you have explained very well why should we measure st at 80
Thank you so much for making this so easy to understand- very appreciated!
Very helpful!! I'm currently a Monitor tech and this video is easy to understand! Thank you!!
Very good teaching

So ST elevation is never positive?
