Cable box shoots lifesaving microprojectiles

Think of what was known as a 'cablebox' (but could be a monitor edge). If these detected things like heart attacks they could have micropellets of lifesaving drugs that shoot as soon as the computer at the TV notices the watcher is critically ill.

This 10 second first response improves the persons health while waiting the 15 minutes for 911. I might have read that 911 CPR is only about 5-20% effective, so this might get it up to 20-50%!

what are the drugs? Well, linking an aptamer (the active glomming part of an antibody) to a drug gives the ability to hyperconcentrate it at a particular area of tissue, so heart concentrating aptamerTPA is one possibility, as is aptamer nitroglycerine.
