flaws in the bioelectrical system that regulates the heart-
beat. 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 meas-
urement 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 ac-
cordance 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 bar chart 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 categories (e.g. systole in the 'High normal' cat-
egory and diastole in the 'Normal' category), the graphical
classification on the device always shows the higher cat-
egory; for the example given this would be 'High normal'.
