Can Pulse Rate Variability be Used to Monitor Compliance with a Breath Pacer?

Pulse rate variability alone may not reliably detect whether a person is following a breath pacer during meditation. In a study with 6 human subjects each completing 2–3 trials, logistic regression and a running standard deviation technique both showed accuracy between 65% and 67% in identifying non-compliance, with notable false positives and false negatives. Existing methods using visual, audio, or motion signals currently perform better for monitoring breath-pacer compliance.
