9.1 Heart rate calculation method
Since the first occurrence of heart rate to heart rate occurred in the second interval T1; second heart rate, heart rate occurred to a third place time interval T2; continuous record 10 times, and then calculated the average interval of 10, must the heart rate per minute. 3s ~ 10s refresh every heart.

9.2 Heart rate meter accuracy and arrhythmia response
Monitor the 20s stable time after figure ECG heart rate a wave group): heart rate display 40bpm ± 5bpm; b): heart rate display 30bpm ±5bpm; c): heart rate display 120bpm±5bpm; d): heart rate display 45bpm±5bpm
A) Couple rhythm — two waves of duration is 1500ms; if the calculation all the QRS complex, heart rate to 80bpm, if only large R wave or S-wave, the heart rate to 40bpm.
B) Slow change couple rhythm — if the calculation all the QRS complex, heart rate to calculate 60bpm, if only large waves, heart rate to 30bpm.
C) Fast couple rhythm — if the calculation all the QRS complex, heart rate as 120bpm.
D) bi-directional contraction — if you calculate the QRS complex, heart rate to calculate 90bpm, if only large waves, heart rate to 45bpm.
