HLSC 4412U Lecture Notes - Lecture 1: Circumflex Branch Of Left Coronary Artery, Coronal Plane, Coronary Circulation
Document Summary
Ra meaning the right arm: the next step that you will apply will be v1 2 and 3, then apply leads 4 5 and 6, last step, apply ll for left leg and rl for right leg. The limb leads (ra, la, ll, rl) go at the four corners of the body. They can go on the arms, legs, torsodoesn"t matter. As long as they are in the four corners. The precordial leads (v1-6) surround the heart, starting from the right side of the chest and walking across to the left mid- axillary line. Depolarized and half are negative or resting: so there is a difference of charge across this set of cells. If we unpause this, everything becomes depolarized and since there is no difference in charge now, there is no dipole and so there is no deflection: moments later a wave of repolarization goes through, pausing halfway through again.
