Heart rate accuracy ±5%
Heart rate alarm Screen icon indicates activated/deactivated status. User selectable.
Tachycardia: 60 to 280 beats per minute
Bradycardia: 20 to 100 beats per minute
Tall T-wave Rejection < 0.8 mV
Heart Rate Averaging The R Series averages the interval between the last 5 detected beats.
On startup, the R Series averages the rate between detected beats
once two beats are detected, until a full 5 beats have been received.
The rate is updated every beat. After this condition is met, the meter is
updated every beat with an average of the last 5 beats.
If a period of time greater than 5 seconds elapses without a beat
detected, the heart rate meter reports a rate of 0 bpm, which is
repeated every 5 seconds.
Accuracy and Response
Time to Irregular Rhythm Averaging over 5 R -R intervals, per AAMI EC 13:2002:
• Ventricular bigeminy (Figure 3a) - 80.5 bpm
• Slow alternating ventricular bigeminy (Figure 3b) - 60.5 bpm
• Slow alternating ventricular bigeminy (Figure 3c) - 120.5 bpm
• Bidirectional systoles (Figure 3d) - 93.3 bpm
