6. Evaluating results
Cardiac arrhythmia:
This unit can identify potential disruption of the heart rhythm when measuring and if necessary, indicates
this after the measurement with the symbol
. If the voice function is activated, the device will an-
nounce:
“A possible cardiac arrhythmia was found.”
This can be an indicator for arrhythmia. Arrhythmia is
an illness in which the heart rhythm is abnormal because of flaws in the bioelectrical system that regulates
the heartbeat. The symptoms (skipped or premature heart beats, pulse being slow or too fast) can be
caused by factors such as heart disease, age, physical make-up, excess stimulants, stress or lack of
sleep. Arrhythmia can only be determined through an examination by your doctor. If the symbol
is
shown on the display after the measurement has been taken, it should be repeated. Please ensure that
you rest for 5 minutes beforehand and do not speak or move during the measurement. If the symbol
appears frequently, please consult your doctor. Self-diagnosis and treatment based on the measurements
can be dangerous. Always follow your GP’s instructions.
WHO classification:
In accordance with the guidelines/definitions of the World Heath Organization, the measurements are clas-
sified and assessed according to the following table:
Blood pressure value category
Systole (in mmHg) Diastole (in mmHg) Action
Grade 3: severe hypertension
> = 180
> = 110
seek medical attention
Grade 2: moderate hypertension
160 – 179
100 – 109
seek medical attention
Grade 1: mild hypertension
140 – 159
90 – 99
regular monitoring by doctor
High normal
130 – 139
85 – 89
regular monitoring by doctor
Normal
120 – 129
80 – 84
self-monitoring
Optimal
< 120
< 80
self-monitoring

The bar chart on the display and the scale on the unit show which category the recorded BMI values fall
into.
If the values of systole and diastole fall into two different WHO categories (e.g. systole in the ‘High normal’
category and diastole in the ‘Normal’ category), the graphical WHO classification on the unit always shows
the higher category; for the example given this would be ‘High normal’.
