Missed Beat
If HR < 120 bpm, no beats are detected for 1.75 times
average RR interval; or if HR
≥
120 bpm, no beats are
detected for one second.
User-selectable
Irr Rhythm
Consistently irregular heart rhythm
User-selectable
Vent Brady
5 consecutive ventricular beats, and ventricular HR < 20
bpm.
User-selectable
Vent Rhythm
5 consecutive ventricular beats, and 20 bpm ≤

threshold value that has been set.
High
ExtremeTachy
HR ≥ Extreme Tachycardia threshold value that has
been set.
High
ExtremeBrady
HR ≤ Extreme Bradycardia threshold value that has
been set.
High
V-Tach
5 consecutive ventricular beats and ventricular HR ≥
100 bpm.
High
Wide QRS
Tachy
Meet tachycardia conditions, and QRS wave width ≥
160 ms.
User-selectable
Non-Sustain VT
3 ≤ The number of consecutive ventricular beats < 5,
and ventricular HR ≥ 100 bpm.
User-selectable
Afib
The RR interval of normal beats must be irregular, and it
can be seen that the obvious f or P waves do not exist.
User-selectable
