I don't think anyone can control their heart muscle directly, but rather through meditation calm themselves and then their heart slows down. And body temperature is not controlled by a muscle so that is probably meditative as well. No comment on the immune system part.

Is there any actual differece to a muscle if you think about it and it happens?

  I'd consider "controlling" something to be more direct, but that's semantics I guess. If I heard "control heartbeat", I'd think more like breathing, where one could "hold their heart" like they "hold their breath". If meditation lowers heartbeat and temperature, I imagine that it's "control" in the strictest sense, but I'd use "influence" or some other term if I was personally describing it.

    You can actually up your heartbeat and temperature too, but you are right, it's more influencing that direct control. A muscle is instant and precise.

    Have you already felt being conscious of your breathing and feeling like being unable to let it go back to automatic control ? Well … > one could "hold their heart" … now that sounds creepy.

  Not all muscles have a spark plug at the tip delivering its own signal to pulse. The sinoatrial node does this in the heart, and it is a reciprocal system like a v8 engine where one side firing begets the other side firing next. When these signals to fire go out of whack, you get fibril movement, which is when a defibrillator is deployed, it shocks the SA node forcing a 'reboot' of sorts and if all goes well, normal sinus rhythm resumes.

Huh? Meditation? It is way easier than that. You can raise heart rate almost instantaneously by imagining that you are doing a rigorous exercise. Slowing it down might be more tricky because you actually need oxygen, but pausing breath with a long slow exhale will probably do the trick.

I can, but it isn't 100% control. It's like putting a (voluntary) damper on an (involuntary) pendulum.
