Being left-handed, I'll offer a left-handed suggestion --

Ditch the direct connection.  Go with a commercially available heart rate sensor, such as a transmitting chest strap heart rate monitor from Polar.

You can buy receivers for this (low carrier frequency) signal that connect up to Arduinos and such:


This board even does noise filtering and some averaging for you, as well as providing raw outputs.

No wires between subject and monitoring gear. Seems like a winner to me.
