The signal for the heart to contract comes from within the heart itself as opposed to from the brain like all the rest of the muscles. This means that if your heart was removed from your chest like in "Temple of Doom", it would still beat !

1. The heart beats as a single unit, via the intercalated disks that connects all the muscle fibers by gap junctions.
2. heart muscles can initiate spontaneous contractions by leaky channels that decrease its resting membrane potential.

I want to keep thinking of it fallically (I made that up), but I found this answer (I like the endurance part of the answer, too): Question: What is the strongest muscle in the human body? Answer: There is no one answer for this question since there are different ways to measure strength. There is absolute strength (maximum force), dynamic strength (repeated motions), elastic strength (exert force quickly), and strength endurance (withstand fatigue).

Some muscles are voluntary, some are involuntary and others are both.
