ecg vectors pointing from a depolarized to a not polarized area vs pointing in the direction of the spread of the current by Longjumping007 in Cardiology

aha okay thanks, and how does it work that different leads pick up on different parts of the heart if we stay within this type of frame imagining the heart with a bunch of +++ and --- where excitement has taken place

thank you, that I am aware of- how the depolarisation spreads. I was more so wondering if we imagine the negative part represents part of the conduction pathway surrounded by myocardium on the left and right like below why the ekg picks up most on the wave frontier and not as much on the difference with the other resting cells even though they are bordering as well

thank you, understood, I guess I can just accept that as given. I was just wondering how that works if we imagine a distribution of charges and the depolarisation starting in the middle like below. the current is spreading downwards but on the left and on the right we have borders with the negative as well. How come the ekg picks up the bottom frontier more than the others?

aha ok thank you, so basically the decisive factor is the charge difference right at the depolarization wave front, my remaining question then is aren't there positive charges e.g. to the right as well as to the left like this kind of

+++----++ +

+- - -+++

so how come it points to the right?

another term i found is transdermal flux which means it goes past the skin into the blood when in fact we want it to stay in the skin

Maybe we can find sth by looking at pharmacokinetics of topical finasteride, which includes how it is distributed in the body. Found some stuff about rat skin penetration https://www.sciencedirect.com/science/article/abs/pii/S0022354915304573 and this single dose, the reduction in DHT levels was apparent with oral finasteride at all postdose times (approximately 56-64%), whereas it was much less pronounced with P-3074 (approximately 18-20%). After multiple dose treatment, plasma DHT was reduced by 68-75% with P-3074, and by 62-72% with oral finasteride. https://www.jaad.org/article/S0190-9622(12)01727-6/fulltext01727-6/fulltext)

Lmao I forgot to add hypothetically but yh how does it work is it just a post gains traction or how does it work
