6. Evaluating results
Cardiac arrhythmia:
This unit can identify potential disruptions of the heart rhythm
when measuring and if necessary, indicates this after the
measurement with the symbol
This can be an indicator for arrhythmia. Arrhythmia is a condi-
tion 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 examina-
tion by your doctor.
If the symbol
is shown on the display after the measure-
ment 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
ly, 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 accord-
ance with the following table.
However, these standard values serve only as a general guide-
line, as the individual blood pressure varies in different 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 pres-
.
appears frequent-
sure 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 values fall into. If
the values of systole and diastole fall into two different catego-
ries (e.g. systole in the "High normal" category and diastole in
the "Normal" category), the graphical classification on the de-
vice always shows the higher category; for the example given
this would be "High normal".
