Answer to Question 1

The dual-chamber pacemaker stimulates the right atrium and right ventricle sequentially (stimulating first the atrium, then the ventricle), mimicking normal cardiac physiology and thus preserving the atrial contribution to ventricular filling (i.e., atrial kick).

Answer to Question 2

Superior vena cava, inferior vena cava, and coronary sinus

This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
