INTERPRETING THE RESULTS
What is systolic and di-
astolic blood pressure?
When the heart ventricles con-
tract to pump blood out of the
heart, the blood pressure reaches
its maximum value in the cycle,
the so-called systolic value. The
blood pressure reaches its lowest
value in the cycle when the heart
ventricles relax. This is the diastolic
blood pressure.
How are blood pressure
values usually catego-
rized?
The classification of blood
pressure published in 1999 by the
World Health Organization (WHO)
and the International Society of
Hypertension (ISH) is as follows:
Classifi-
cation
SYS
(mmHg)
DIA
(mmHg)
Grade 3 HT ≥ 180 ≥ 110
Grade 2 HT 160 – 179 100 – 109
Grade 1 HT 140 – 159 90 – 99
High normal 130 – 139 85 – 89
Normal 120  129 80 – 84
Optimal < 120 < 80
HT = Hypertension (high blood pressure)
IMPORTANT
Only a medical doctor can determine your
normal blood pressure range. Please see
a doctor if your measurement results are
outside of this range.
Recognizing irregular
pulse
The device recognizes irregular
pulse (arrhythmia) if the heartbeat
fluctuates while measuring the
systolic and diastolic blood pres-
sure. The blood pressure monitor
records heartbeat intervals and
calculates the average value
during each measurement. If an
average value is greater than or
equal 25%, the measurement re-
sult also displays a warning signal
for irregular pulse.
The warning “irregular pulse”
shows that an irregular pulse
has been determined during the measure
-
ment, which might indicate arrhythmia.
Generally, this is NOT a cause for concern.
However, if the symbol is displayed fre
-
quently, we recommend that you speak
with your doctor. The device does not repla
-
ce a cardiology examination but provides an
early detection of irregular pulse.
