The calculation method is as follows.
[Distance (mm/beat) × Time (sec/square) = RR interval (sec/beat)]
1 beat is a value calculated by 1 second (1 second/beat), and the number of beats per second must be calculated to
calculate the heart rate, and to do so, the RR value is 1/RR value.
It uses a conversion factor and converts it to a general unit of minutes (beat/min).
[1 beat/sec x 60 sec/min = 60 beats/min.]
Pause is recognized as pause when no QSR bit for more than 4 seconds occurs.
If the QRS label does not occur in the detail plot and the graph continues flat for 4 seconds, it is recognized as a
pause.
4) Amplitude selection drop box
This is a function to select the voltage of the ECG displayed on the Seconds Strip Plot. The initial Amplitude
setting value is “x1.0” and the user can select and use the desired value among the values presented in the drop
box.

5) Time Range Selection Drop Box
It is a part that selects the range of the ECG time domain displayed on the Seconds Strip Plot. As shown in [Figure
