So, is someone with a pacemaker technically a cyborg? Options

[Wounded Ronin]

In RPGs like Shadowrun and others, we deal with the concept of the cyborg a lot...part man, part machine.

I understand that there are some people in Europe who have gone so far as to have cameras sugrically mounted on their skulls or LED lights implanted under their skin and then claim that they are cyborgs and whenever someone doesn't like what they have done they are experiencing cyborg discrimination.

But recently I have been studying about cardiac diseases and in my textbook I learned about how a pacemaker is implanted in the chest and basically interfaces directly with the heart via electrical charges to help it beat correctly.

Wouldn't a guy with a pacemaker be considered a cyborg? Considering the depth of implantation and the fact that the pacemaker is governing a key part of his physiology, surely that guy is much more a cyborg than someone who decided to drill a webcam onto his skull that doesn't actually directly interface with his body.

If I were a Shadowrun GM, and someone asked me if bolting a camera to your skull with surgical screws would cost Essence, I would say maybe not, because it's so superficial and it doesn't really interface with your body. If someone asked me if implanting a device that would dictate their heart rhythm would cost Essence, I would say maybe yes.
