Fig. 8.9.2 Summarised results of the heart rhythm analysis and heart rate in beats per minute (bpm) over the
entire measurement of a report with slight arrhythmia
Positive peaks result from irregular heartbeats, which have a significantly reduced time
interval from the previous heartbeat compared to the average. Negative peaks in the pulse
rate, on the other hand, indicate a significantly greater time interval between the irregular
heartbeat and the previous normal heart rate, compared to the average.
Fig. 8.9.3 shows a heart rate with the presence of atrial fibrillation. The heart rate is strongly
irregular over the entire measurement. The fluctuations of the heart rate occur chaotically
throughout the entire measurement.

report with absolute arrhythmia
The third section of the measurement report consists of the original pulse curve. A wave in
the pulse curve represents one heartbeat. For the heart rhythm analysis, points are
detected in the pulse curve, which behave equivalent to the R peaks in an ECG. These
points are shown in the form of R peaks in the original pulse curve to illustrate a
detected/recognised heartbeat (see Fig. 8.9.4). Black R peaks symbolise a regular
heartbeat, yellow an irregular heartbeat (such as extrasystole) and red R peaks an
extremely irregular heartbeat based on absolute arrhythmia (suspected atrial fibrillation).
