What’s the correct sequence of an impulse moving through the heart?
- Sinoatrial (SA) node “pacemaker” in RA
- Wave of impulses through muscle of atria cause contraction
- Artioventricular (AV) node stimulated in floor of RA -> bundle of his and septum-> purkinje fibers in walls of ventricles
- Ventricles contract
