Artificial Heart Approved for Human Testing

[bunnies rule all]

I spotted this article off facebook from IFLS and thought it would be interesting to share and discuss:

My first thought however was how does an artificial heart respond to changes from relaxation to exercise or an increase in adrenaline exposure? Anyone have any insight on this?

Well, with an infrared chemical tester, you could theoretically detect adrenaline and such in the body, and be able to know how to respond, or alternatively the heart could always be beating at like, 210 beats per minute, and you could be well over the limit 24/7, but honestly I don't think they really do that; you could theoretically respond by measuring the old hearts response, or what's left of it, or basically have some form of chemical tester.

I assume its the microelectronics and sensors part it mentions in the article.
