You think the "heart beat tracking" technology is for real? I didn't buy into that for a second. Tech can't track organs, at the very least Adrian would need to be rigged with nanites like they did with Malcolm and Earth-2 Laurel. Helix just told Felicity what she wanted to hear so they could use her to get Cayden out of ARGUS. The so called "heartbeat tech" was probably little more than a key to activate the EMP Adrian probably rigged to the computer hours before, or the tech Felicity got was in fact the EMP itself. Adrian's name coming up on the monitor was probably just a taunting trick like "You wanted me, here I am" then BANG!

Felicity isn't using her common sense in her desire for vengeance which is probably what Adrian was counting on, thereby making her easy to manipulate and turn against Oliver in her very attempts to stop him.
