Review all lab homework, including “Reviewing and Understanding Your Knowledge”) 3. In general, when reviewing images of blood vessels, the conventional way to depict veins is by coloring them blue and arteries red (May not be universal) Chapter 20 (The Heart) 1. EKG—P, QRS, and T waves; What do these electrical and mechanical events correspond to? EKG=P-QRS-T waves P wave: depolarization (contraction) of atria QRS wave: depolarization of ventricle T waves: repolarization (goes back to normal) 2. Conduction system of the heart; Master pacemaker electrical impulse: SA node - AV node - Bundle of HIS - L&R bundle - Pukinje fibers. SA node - master pacemaker.
