Hello everyone, I recently got a job on a CMU and I am learning how to do ECG's. I read this statement about them and I'm a little confused by it, can someone please explain it? To obtain a 12 lead ECG, four wires are attached to each limb and six wires are attached at different locations on the chest. The total of ten wires provides 12 views (12 leads) I just dont understand how ten wires allows for 12 views. Any advice? Thank you!
