A Note on CHR Accuracy
Even though the CSX uses the most advanced
digital CHR system available today, CHR
monitoring may be a bit less accurate than a chest
strap, since the heart rate signals are much stronger
at the chest.
About 5% of the population cannot be picked up
by any CHR system. This is because their heart is
positioned in a more up-and-down manner in their
chest, as opposed to leaning over to one side. This is
not a health or safety issue.
See Appendix A for details.
