CARDIOTACHOMETER
Precision and response of the heart rate monitor with regular rhythms:
Heart Rate Measurement:
Range = 20
[1/min]
to 250
[1/min]
.
Resolution = 1
[1/min]
.
Calculation and display of heart rate: It is updated every 2 seconds, average of the last 4 values.
Heart Rate Accuracy: ± 10% of reading or ± 5 [1 / min] (whichever is greater).
Bradycardia Alarm: 20
[1/min]
to 245
[1/min]
, in steps of 5
[1/min]
.
Tachycardia Alarm: 25
[1/min]
to 250
[1/min]
, in steps of 5
[1/min]
.
Maximum HR alarm system delay
Tachycardia: 3.8s ± 0.1s.
