Microlife WatchBP Home A is the world’s rst digital blood pressure measurement device that strictly follows European Society of
Hypertension (ESH)1, 2 and American Heart Association (AHA) recommendations for home blood pressure measurement. Using the
WatchBP Home A device helps you collect accurate home blood pressure measurements your doctor can trust. This WatchBP Home A
device has been clinically validated according to the ESH protocol 3.
# WatchBP Home A BT is the same WatchBP Home A with Bluetooth (BT) capability.
Indications For Use
The Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model WatchBP Home A BT (BP3MX1-3C) is a device intended
to measure the systolic and diastolic blood pressure and pulse rate of an adult individual with arm cuff circumference sizes ranging
from 22 -42 cm by using a non-invasive oscillometric technique in one inatable cuff being wrapped around the upper arm.
The device detects the appearance of atrial brillation during measurement and gives a warning signal with the reading once the
atrial brillation is detected.
The memory data can be transferred to the PC (personal computer) running the WatchBP Analyzer Home software by connecting the
monitor via cable. The device can also be used in connection with smart mobile devices running the APP and via Bluetooth.
The device is intended for use by patient at home or by health care givers in primary care settings.

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.

WatchBP Home A BT has an extended measurement period
and allows morning measurements between 04:00 - 12:00
and evening measurements between 18:00 - 24:00.
Outside these times, measurements cannot be
taken and the symbol on the right will be displayed
on the screen.
When measurements
have been carried out
for the full 7 days, the
doctor symbol will

pressure measurement with Ab detection. In «USUAL»
mode, three consecutive measurements are taken
automatically at 15 second intervals. The results are
averaged and displayed. The averaged readings are
automatically stored for later evaluation by your doctor.
250 measurements safely stored
The WatchBP Home A BT device can store up to 250

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.
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.

BT
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.

14
Step 5
Sit upright and lean comfortably against the chair’s
backrest. Press the start button. The device will
initiate a 60-second countdown in «DIAG.» mode or a
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
relax as you wait for the second measurement. The
second measurement will start after 60-seconds. During
this time avoid any movement.

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 Ab icon is
displayed. If the Ab icon is displayed after a blood
pressure measurement follow the instructions on page
21.

* 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 debrillators. People with pacemakers or
debrillators 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 in
old 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 conrm the presence of atrial
brillation by using an EKG. Atrial brillation can
sometimes come and go. So a doctor may not see its
symptoms 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. Diagnosing atrial brillation
earlier and followed by treatment can lower the
chances of getting a stroke.

18
Atrial Fibrillation Detector
The WatchBP home A 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 arrhythmia (irregular heart beat) other than
atrial brillation might be present. In such a case it is
still recommended to pay a visit to the doctor.
For people with pacemakers or debrillators it is
not recommended to use the WatchBP Home A for
diagnosing atrial brillation.
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 specically 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 ofce. 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 it is suggested
to perform an EKG to determine the exact rhythm
abnormality.
