The heart muscle contracts and relaxes when calcium is released from a reservoir inside into the muscle cell and then pumped back quickly.

BBC: Gene link to inherited heart disease

This is fascinating to people interested in the question of how genomes switch from state to state say, from the state of a stem cell, which can grow into almost anything, to that of a muscle cell, committed to an existence of contraction and expansion.

ECONOMIST: Human genomics

Scientists have already identified the genes responsible for building muscle and increasing red cell production.
