List five functions of a cardiac pacemaker

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 !
