Okay I'm driving myself nuts tonight. So far I got that it's a 12 lead with only 10 leads actually attached b/c some are reading different pathways 12 leads = lead 1,2,3,AVR, AVL, AVF, V1,V2,V3,V4,V5,V6
Lead 1 is reading from + L arm to - R arm
Lead 2 is - R arm to + L foot
Lead 3 is - L arm to + L foot
Where I'm getting tripped up is the L arm seems to be able to generate both + and negative depending on what it's reading is that correct? Because originally I'm thinking that the one electrode is either going to be + or - I get that they're bipolar. Or maybe I don't fully and that's what's tripping me up! Then I started thinking that maybe there are 2 electrodes attached one for positive one for negative
but that didn't really make sense.
So basically I'm thinking that the electrode placed isn't necessarily capturing the polarity of positive vs negative at that point (I hope that makes sense I went back over definitions of polar, poles etc...ad nauseam) but it captures the impulse travelling whatever points are being analyzed.
Dubin's book is great...but some things he took for granted that some of us that have to work harder at understanding things would just get!
Thanks to anyone that can dumb this down for me or tell me that I'm finally on the right train of thought. Many hours later!
