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, repeat the measurement.
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.
Risk indicator
The measurements can be classified and evaluated in
accordance with the following table.
However, these standard values serve only as a general
guideline, as the individual blood pressure varies in differ-
ent people and different age groups etc.
It is important to consult your doctor regularly for advice.
Your doctor will tell you your individual values for normal
blood pressure as well as the value above which your
blood pressure is classified as dangerous.
The classification on the display and the scale on the unit
show which category the recorded blood pressure val-
ues fall into. If the values of systole and diastole fall into
two different categories (e.g. systole in the ’High nor-
mal’ category and diastole in the ’Normal’ category), the
graphical classification on the device always shows the
higher category; for the example given this would be
’High normal’.
