That’s a good question! As a layman I would assume there’s no way to read/detect the hormones that would demand acceleration of the heartbeat? So one has to take it easy for the rest of their life? Or maybe there’s a way to manipulate it manually?

If the heart is no longer the weak link, can you permanently increase level of blood flow to something akin to moderate exertion? Presumably you are now limited by what the veins can handle, but maybe they have more flexible performance characteristics?

Layman, but I imagine if your blood is flowing to fast doesn't help much the lungs have certain diffusion rates, the waste products wouldn't be increased because your not doing as much work. There is probably an optimal point where anymore just doesn't really matter.

I beat there is some psychological factors to thought you don't have a beat or pulse that is probably unsettling

IIRC this problem affects heart transplants as the nerve that controls the speed of the heart is severed during the operation.

Can't implants read from that nerve? Or the issue is that the "protocol" is hard to reverse?
