About blood pressure
Blood pressure is the force of blood pushing against the walls of
arteries. It is typically measured in millimeters of mercury (mmHg).
Systolic blood pressure is the maximum force exerted against
blood vessel walls each time the heart beats. Diastolic blood
pressure is the force exerted on blood vessels when the heart
is resting between beats.
An individual’s blood pressure frequently changes throughout
the course of a day. Excitement and tension can cause blood
pressure to rise, while drinking alcohol and bathing can lower
blood pressure. Certain hormones like adrenaline (which
your body releases under stress) can cause blood vessels to
constrict, leading to a rise in blood pressure.
If the blood pressure measuring numbers become too high,
it means the heart is working harder than it should.
Cardiac arrhythmia
− If the blood pressure monitor detects an irregular heart
rhythm two or more times during the measuring process, the
arrhythmia indicator
22 will be shown on the display 1 .
− Irregular heart rhythm is defined as a heart rhythm that is
either 25 % slower or faster than the average heart rhythm.
− Consult your physician if the arrhythmia indicator
frequently appears with your measurement results. At
the same time, make sure you comply with the basic rules
for correct measurement of blood pressure (see chapters
“Advice on use” and “Performing a measurement”).
