Ectopic pacemakers have to do with the section of electricity between the atria and ventricles, which is between the AV junction and ventricles. The SA node and AV junction are both within the atria. The SA node and right bundle branch is too large of a section, but also too specific when talking about just right bundle branch, it would need to be both right and left. AV junction and left bundle branch is too large and the ectopic pacemaker does not extend down to the left bundle branch.
