USUAL
Taking measurements using WatchBP Home A
Prior to each measurement, use the Mode Switch on the
right side of the device to select the proper measurement
mode. The two options include:
«DIAG.» (Diagnostic) or «USUAL» (Usual) mode.
DIAG.
10
USUAL
«DIAG.» Mode
The «DIAG.» mode should be selected as requested
by your doctor when blood pressure is measured in
accordance with the measurement guidelines of the
European Society of Hypertension (ESH).
DIAG.
No measurements on non-work days
In «DIAG.» mode, blood pressure measurements are
taken on 7 consecutive working days (or normal
week days). No readings should be taken on
«non-working» days (or particularly relaxing days)
in this mode!
Two sets of measurements per day
ESH guidelines recommend one double measurement
taken in the morning between 06:00 - 09:00 and one in
the evening between 18:00 - 21:00. Always perform
measurements before taking your medication,
unless otherwise directed by your doctor.

Eight steps for measure blood pressure properly
Step 1
Avoid taking measurements directly after eating,
drinking or smoking. Allow at least one hour between
these activities and measurement of your blood pressure.
1 Hour Before
14
Step 2
Prepare a chair and table for the measurement. The
chair should have a vertical back-rest and the table
should allow your upper arm to rest at the same height
as your heart.
Step 3
Remove all clothing covering or constricting the arm to
be measured. Apply the cuff. Make sure the lower edge
of the cuff is exactly 2–3cm from the inner fold of your
arm. The tube connecting the cuff to the device should
be placed on the inside of the arm. (Additional visual
instruction can be found on the cuff)
Step 4
Sit down and relax for at least ve minutes prior to the
measurement.

15-second countdown in «USUAL» mode. During the
measurement do not move, cross your legs, or tense
your arm muscles. Breath normally and do not talk.

Step 6 (in «DIAG.» mode)
One measurement cycle includes two measurements.
Once the rst measurement is complete, continue to

Step 8 (in «DIAG.» mode)
When seven days of measurements have been collected,

to take your WatchBP Home A device with you on your
next visit to the doctor. (Note: the doctor symbol is only
displayed for measurements in «DIAG.» Mode.)

Special Function
Atrial brillation detection
This device is designed to screen for atrial brillation
during blood pressure measurements both in
«USUAL» Mode and «DIAG.» Mode. If atrial
brillation is detected during all readings of the triple
measurements in usual mode or all four readings
of one day in diagnostic mode, the Ab icon
displayed. If the Ab icon is displayed after a blood
pressure measurement follow the instructions on page
21.

is
IAD
Atrial brillation, a major cause of stroke can be detected by
*
this device. However, not all risk factors for stroke, including
atrial utter, may be detected by this device.
This device may not detect atrial brillation in people with
*
pacemakers or debrillators. People with pacemakers or
debrillators should therefore not use this device to detect
atrial brillation.
About Atrial Fibrillation
Atrial brillation is a common heart rhythm problem
and a common cause of major strokes. It affects more
than 2 million people in North America. It is more
common with older age and found in 10% of people
over 80 years old. About 20% of all strokes are caused
by atrial brillation. The elderly, or those with high blood
pressure, diabetes or heart disease are more likely to get
a stroke if they have atrial brillation.
Atrial brillation is a rhythm problem that can last from
a few minutes, to days or weeks and even years. Atrial
brillation can lead to the formation of blood clots in the
upper chambers of the heart (the atria). These clots can
break off and ow to the brain causing stroke. The use
of blood thinners, such as warfarin , can lower the risk of
stroke in patients with atrial brillation.
A doctor can conrm the presence of atrial
brillation by using an EKG. Atrial brillation can
sometimes come and go. So a doctor may not see it
on regularly scheduled visits.
One sign of atrial brillation is palpitations. But,
many people don’t feel anything. These people can
still get a stroke and should be checked for atrial
brillation regularly. Finding atrial brillation earlier
and followed by treatment can lower the chances of
getting a stroke.
19
EN
Atrial Fibrillation Detector
The WatchBP home can screen for atrial brillation
during blood pressure measurement.
Some people may have atrial brillation occasionally
that lasts longer than a day. In this situation the WatchBP
Home A allows frequent screening on multiple days for
optimal diagnosis of atrial brillation.
Sometimes the device might falsely detect atrial
brillation which can have two causes:
1) The arm has moved during blood pressure
measurement. For this reason it is of essential
importance that the arm is kept still during the
measurement.
2) Some other arrhythmia (irregular heart beat) than
atrial brillation might be present. In such a case it is
still recommended to pay a visit to the doctor.
20
For people with pacemakers or debrillators it is not
recommended to use the WatchBP Home A.
Measurement
If atrial brillation is detected during all readings of
the triple measurements in «USUAL» Mode or all
four readings of one day in «DIAG.» Mode then atrial
brillation is most likely present.
Since atrial brillation sometimes lasts for only a
few minutes. It is recommended to perform another
measurement session one hour later. If this also shows
the presence of atrial brillation then a doctor should
be seen. It is recommended to take the device when
visiting the doctor.
Atrial brillation detection instructions
• Use this device regularly, once per week, or once per
month to screen for atrial brillation.
• If atrial brillation is detected during all readings of the
triple measurements, another measurement session
should be done approximately one hour later.
• If this last reading shows atrial brillation contact your
doctor.
• Take this device with you when you see the doctor.
Information for the doctor
This device is designed to detect atrial brillation and
false negative readings are very rare. Though it is
programmed to specically detect atrial brillation,
frequent premature beats, marked sinus arrhythmia
or other rhythm abnormalities might cause false
positive readings. If atrial brillation is detected by
the device at home, we suggest another reading done
in the doctor’s ofce. If the atrial brillation icon is
not displayed then the previous abnormal readings
may have been due to transient atrial brillation.
If the atrial brillation icon is displayed then EKG
performance is suggested for determining the exact
rhythm abnormality.
