What are systolic pressure and diastolic pressure?

Diastolic
When ventricles contract and pump blood out
of the heart, the blood pressure reaches its
maximum value in the cycle, which is called
systolic pressure. When the ventricles relax,
the blood pressure reaches its minimum value
in the cycle, which is called diastolic pressure.
Irregular Heartbeat Detector
ABOUT BLOOD PRESSURE
An irregular heartbeat is detected when a heartbeat rhythm varies while the device is
measuring systolic pressure and diastolic pressure. During each measurement, the
blood pressure monitor will keep a record of all the pulse intervals and calculate their
average value. If there are two or more pulse intervals with an average difference
between each interval of more than ±25%, or if there are four or more pulse intervals,
with an average difference between each interval of ±15%, then the irregular
heartbeat symbol will appear on the display with the measurement result.
ABOUT BLOOD PRESSURE
Why does my blood
pressure fluctuate
throughout the day?
Is the result the same if measuring on the
right arm?
Why do I get a different blood pressure at
home compared to the hospital?
1. Individual blood pressure varies throughout the day. It is also affected by the
way you tie your cuff and your measurement position. It is recommended that
you take your measurement under the same conditions.
2. If you take medicine, your pressure may vary more.
3. Wait at least 3 minutes between measurements.
The blood pressure is different throughout the day due to weather,
emotion, exercise, etc. Also, there is the “white coat” effect, which means
blood pressure usually increases in clinical settings.
It is okay to measure on either arm, however; there may be different results
for some people. We suggest you measure the same arm every time.
If the cuff is tied properly.
If the cuff is too tight or too loose.
If the cuff is tied on the upper arm.
If you feel anxious.
Take 2-3 deep breaths before you begin measuring.
Relax for 4-5 minutes until you are calm.
What is the standard blood pressure classification?
The chart on the right is the
standard blood pressure classifi-
cation published by American
Heart Association (AHA).
Please consult a physician if your result falls outside the range. Please note
that only a physician can tell whether your blood pressure value has
reached a dangerous point.

Pay special attention to the following when you
measure your blood pressure at home:
The appearance of the IHB icon indicates that a pulse irregularity consistent with an
irregular heartbeat was detected during measurement. Typically this is NOT a cause
for concern. However, if the symbol appears often, we recommend you seek medical
advice. Please note that the device does not replace a cardiac examination, but serves
to detect pulse irregularities at an early stage.
