why would one want to control his or her heartbeat? You do know what consequences a "not beating" heart has on you?
I dont know if it`s possible, maybe, maybe it`s hard to find a willing subject for that kind of experiment?
But since sword swallowers are capable of controling their gag reflex, and didgeridoo players are capable of controling the flow of air through their lungs.
I wouldnt be suprised if the list of organs which one can train to control or disrupt their usual process is long.
