Evaluating the results
General information about blood pressure
• Blood pressure is the force with which the bloodstream
presses against the arterial walls. Arterial blood pressure
constantly changes in the course of a cardiac cycle.
• Blood pressure is always stated in the form of two values:
– The highest pressure in the cycle is called systolic blood
pressure. This arises when the heart muscle contracts
and blood is pumped into the blood vessels.

– The lowest is diastolic blood pressure, which is when
the heart muscle has completely stretched back out and
the heart fills with blood.
• Fluctuations in blood pressure are normal. Even during
repeat measurements, considerable differences between
the measured values may occur. One-off or irregular
measurements therefore do not provide reliable informa-
tion about the actual blood pressure. Reliable assessment
is only possible when you perform the measurement
regularly under comparable conditions.
Cardiac arrhythmia
This device can identify potential disruptions of the heart
rhythm when measuring and, if necessary, indicates this
after the measurement with the symbol
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

determine any arrythmia during an examination.
