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.
What is Irregular Heartbeat?
An irregular heartbeat is a heartbeat rhythm that varies by
more than 25% from the average heartbeat rhythm detected
while the unit is measuring the systolic and diastolic blood

pressure.

If such an irregular rhythm is detected more than twice
during measurement, the irregular heartbeat symbol (
appears on the display when the measurement results are
displayed.
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.
