The answers can be :

coordinate the electrical signaling of the heart between the upper and lower chambers of the heart ;

prevent dangerous arrhythmias from occurring in patients who suffer from long QT syndrome ;

-  
use low-energy electrical pulses to mimic the heart’s own electrical signaling ;

speed up a slow heart rhythm ;

 control a fast or an irregular heart rhythm.

Hope this helps !
