HR Averaging Method
Method 1
Heart rate is computed by excluding the minimum and maximum
values from the 12 most recent RR intervals and averaging the
residual 10 RR intervals.
Method 2
If each of three consecutive RR intervals is greater than 1200 ms,
then the four most recent RR intervals are averaged to compute
the HR.
