Heart Rate
Averaging The E Series averages the interval between the last 5 detected beats. On startup, the
E 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) - 40 bpm
• Slow alternating ventricular bigeminy (Figure 3b) - 60 bpm
• Rapid alternating ventricular bigeminy (Figure 3c) - 120 bpm
• Bidirectional systoles (Figure 3d) - 90 bpm
