all other muscles in the body are voluntary whereas the cardiac muscles are controlled by SA node which is involuntary.
Heart is the only organ in human body Which is myogenic (works itself) due to presence of mitochondrians all over the heart surface.
since mitochondrians are full of energy, the heart muscles derives this energy and work on it's own.
e.g During open heart surgery a human heart is fully taken out off the body and operated separately.
The mitochondria helps the heart to survive
