I could have made a lot of money off people that say "HRM's work on my 
horse." Being a nice guy I've never collected ;-) . Roger explained it 
well. There are three issues, placement, polarity (you might have to 
turn it upside down) and operator competence. The sensor is not the 
problem - 99.9% of the time it's the person using it.

Kidding aside. The HRM doesn't measure heart rate. It measures the 
electromagnetic radiation generated with the nerve firing that controls 
the heart. It does the same thing an EKG does. There are subtleties 
associated with this radiation and it does vary a little from individual 
to individual. The operator needs to understand this to use the sensor 
properly. It's no different than an stethoscope. A poor operator with a 
stethoscope will make the same mistakes - but most likely the rider will 
not detect them.
