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.
