The heart is able to beat by itself by means of the pacemaker (Primarily the Sino-atrial node). The role of the brain is to regulate the heart rate. Increasing it via sympathetic stimulation or decreasing it via parasympathetic stimulation.
It depends on the length of time to which you are referring.
The heart, without blood supply will absolutely not keep beating after it has been removed from the human body. It may retain one or two beats, but only because the heart is a muscle and functions like other muscles. It has an independent, internal "pacemaker" if you will, that would tell it to keep beating. The electric impulse carried out by the heart is based on the sodium pump like all other muscles. So, it may beat once or twice weakly before stopping altogether as it uses up any remaining sodium.
if its severed from the brain it shouldn't beat anymore. but automaticity may be the answer you are looking for.

They are both essential to survival.
