3. Using the Unit  
Your blood pressure monitor includes an irregular heartbeat feature. Irregular heartbeats  
can influence the results of the measurement. The irregular heartbeat algorithm  
automatically determines if the measurement is usable or needs to be repeated. If the  
measurement results are affected by irregular heartbeats but the result is valid, the result is  
shown together with the irregular heartbeat symbol (  
). If the irregular heartbeats cause  
the measurement to be invalid, no result is shown. If the irregular heartbeat symbol (  
is shown after you have taken a measurement, repeat the measurement. If the irregular  
)
heartbeat symbol (  
) is shown frequently, please make your doctor aware of it.  
• If you move during measurement, the movement error symbol ( ) will appear on the  
display. Keep still and repeat the measurement.  
Note: Wait 2-3 minutes before taking another blood pressure measurement. Waiting between readings  
allows the arteries to return to the condition prior to taking the blood pressure measurement.  
Warning:  
Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of  
your doctor.

7. Some Useful Information about Blood Pressure  
What is Blood Pressure?  
Blood pressure is a measure of the force of blood flowing against the walls of the arteries.  
Arterial blood pressure is constantly changing during the course of the heart’s cycle.  
The highest pressure in the cycle is called the Systolic Blood Pressure; the lowest is the  
Diastolic Blood Pressure.  
Both pressure readings, the Systolic and Diastolic, are necessary to enable a doctor to  
evaluate the status of a patient’s blood pressure.  
EN  
What is Irregular Heartbeat?  
Normal Heartbeat  
An irregular heartbeat is a heartbeat rhythm that varies by  
more than 25% from the average heartbeat rhythm detected  
Pulse  
while the unit is measuring the systolic and diastolic blood  
pressure.  
Blood pressure  
Irregular Heartbeat  
If such an irregular rhythm is detected more than twice  
during measurement, the irregular heartbeat symbol (  
Long  
Short  
Pulse  
)
appears on the symbol when the measurement results are  
displayed.  
Blood pressure  
What is Arrhythmia?  
Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-  
electrical system that drives the heartbeat. Typical symptoms are skipped heartbeats,  
premature contraction, an abnormally rapid (tachycardia) or slow (bradycardia) pulse.  
23  
 
7. Some Useful Information about Blood Pressure  
Why is it a Good Thing to measure Blood Pressure at Home?  
Many factors such as physical activity,  
anxiety, or the time of day, can  
Upper curve: systolic blood pressure  
Lower curve: diastolic blood pressure  
200  
influence your blood pressure. A single  
measurement may not be sufficient for  
an accurate diagnosis. Thus it is best to  
try and measure your blood pressure at  
the same time each day, to get an  
accurate indication of any changes in  
blood pressure. Blood pressure is  
typically low in the morning and
