Years ago there was a film with this exact premise. An offbeat scientist (Jeff Goldblum) invents the first artificial heart, and a cardiologist (Donald Sutherland) installs it to save a patient's life. The patient becomes anxious because her pulse has been replaced with a constant shshshshshsh sound. The film was Threshold (1981).

Shut up, Wesley!

A couple of years ago I invested $10 in a metal travel wallet that functions as a de facto Faraday Cage. Or you could spend 8x that on a microwoven stainless steel version...
