Skeletal muscle: Produces movement, maintains posture, stabilises joints and generates heat
Smooth muscle: Found in the walls of hollow organs
Cardiac muscle: Exists only in your heart
It works automatically and constantly without ever pausing to rest.
every other types of muscles get tired except cardiac muscle, why?

the heart was made that way.. it has something to do with the action potentials it produces and the release of substances like calcium that makes it tire after a very long time.. and i mean after a very long time.. that's why we've got to take care of it cause it will never ever regenerate..

It definitely does get tired. If you take care of your body and not do any of the bad things that puts stress on any of your muscles then they dont have to work any more or any less. They are able to pace theirselves to an even balance. Years of abuse to your cardiac muscle has unconscious ways of letting you know to stop or slow down. Just most of us dont pay any attention and keep truckin.

of course!!!! that must be why skeletal muscles are called skeletal muscles, smooth muscles are called smooth muscles (I see a trend here, bear with me . and i think that , that's why cardiac muscles are called cardiac muscles!!!!)
anyway what you say isn't really true. the reason that your heart doesn't seems to get tired is that it rest half the time!!!! in between beats.
and when it really gets tired you get heart attacks and need to get a pacemaker to get your cardiac muscles going and if even that won't help then you either get a heart lung machine to do everything for you or you just......................die.
anyway there are worse things than dying.

This muscle is different because it has a small electric shock that causes it to contract/beat. Thus the muscle isn't actually labouring so much as it is simply "reacting". Sometimes the little electric shock can start going off-beat and causing complications which is when surgeons can put in a pace-maker to correct the rhythm when necessary.
