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 the irregular heartbeat symbol (
) is shown
frequently, please make your doctor aware of it.
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.
