• Recording Interval
  A time interval from 1 to 10 minutes (default: 2 min). The final value of all HRV metrics is computed with the RR-values recorded during this time span. Note that the displayed metrics and the animation of the histogram and Poincaré plot during an active recording are preliminary and based on the values recorded so far. Only at the end of the recording interval these metrics will reach their final values.


• Artefact Filter
  RR-values that deviate more than a certain percentage from the sliding average of the last 5 values are considered to be artefacts. These outliers are filtered out and not considered in the computation of the HRV metrics. The default filter limit is 25 percent.


• Stress Alarm
  This slider can be used to set an upper limit for the stress index. When the limit is exceeded during a continuous recording an acoustic signal will be played. You can define the sound of the signal (default: system notification).


• Continuous Recording
  With this checkbox you can switch to continuous recording mode. In this mode the recording will not stop at the end of the recording interval but continue until stopped manually. However, the computation of the HRV metrics uses a sliding time interval i.e. only the RR-values recorded within the last elapsed interval are used.


• Automatic Start
  If this box is checked the recording starts automatically as soon as a heartrate sensor is connected.


• End-of-Recording Signal
  Checkbox for activating an acoustic signal indicating the end of the recording interval. You can define the sound of the signal (default: system notification).


• Display Mode
  Choose beween light and dark display modes.
