Chapter 1 Preface
1.1 Brief Introduction of Ambulatory Blood Pressure Monitoring
Ambulatory blood pressure monitor is an instrument for monitoring human’s blood
pressure automatically during certain period (normally 1-2 days) with certain intervals
upon actual situation. Blood pressure readings in different periods under different
conditions would be analyzed and then blood pressure diagnosis would be given
accordingly.
During 24 hours in a day, human blood pressure is not fixed, but fluctuates within a certain
scope. Spot measurement of blood pressure in clinic office may not reflect the patient
blood pressure situation accurately, especially for the patients whose blood pressure only
high on some certain time during a day. The 24-hour ambulatory blood pressure
measurement would indicate the whole day blood pressure fluctuation and be able to help
finding the patients whose blood pressure only high on some certain time during a day.
It is also important to conduct 24-hour ambulatory blood pressure measurement for those
confirmed hypertension patients. Research shows half of hypertension patients who
believe their blood pressures were controlled well are found that their blood pressure are
still unstable during 24-hours by using ambulatory blood pressure measurement, their
blood pressures rise up in the morning and/or in the afternoon, or rises up at night, it
means their blood pressure is not controlled ideally. This well explained why confirmed
hypertension patients who already taking medication and feel good in blood pressure
control still suffer from renal damage. 24-hour ambulatory blood pressure monitoring can
help patients to learn their blood pressure fluctuation trend and doctor would be able to
provide accurate short, medium or long-term medication solution accordingly. This would
help to control their blood pressure well and avoid further damage of target organs e.g.
cardio, brain and kidney. Obviously, Ambulatory blood pressure monitoring is superior to
spot clinical blood pressure measurement, and gradually becomes an important method
to evaluate the treatment effecacy of hypertension.
Compare to clinical or home blood pressure spot measurement, the ambulatory blood
pressure monitoring has below strength:
a) Eliminating the measurement contingency and some other affecting factors i.e. emotion,
movement, eating, smoking, drinking, etc.
b) Reflecting the 24 hours blood pressure fluctuation accurately upon much more readings
covering the whole day.
c) Help to improve hypertension diagnosis quality, i.e. to have borderline hypertension
patients getting timely treatment. These patients usually do not feel any symptom at early
stage.
d) Providing guidance on medication. In many cases it could be used to evaluate
medication effecacy, help to select drugs, and adjust dosage and drug administration time.
e) Providing accordance on target organs damage analysis (especially for organs which
used to be caused by hypertension). For instance, the hypertension patients with
myocardial hypertrophy, fundus dynamic vascular lesions or renal function changes, the
blood pressure difference between day and night is smaller than usual.
f) To predict the time of sudden attack of cardiovascular and cerebrovascular disease in a
day. Usually, it is most frequent that the stroke happens due to a sudden rising of blood
pressure in early morning.
g) Ambulatory blood pressure measurement is very important for prognosis. Compare with
normal blood pressure, patients with high blood pressure in 24 hours have higher mortality
and incidence of cardiovascular disease than those with low blood pressure in 24 hours.

6
For the following hypertension types, Ambulatory blood pressure monitoring is particularly
helpful for diagnosis.
1. White-coat hypertension
White-coat hypertension is for the cases that the blood pressure is constantly high in
hospital or clinic office but normal out of hospital or clinic office. And this kind of situation is
repeatable. White coat hypertension is very common. About 15% of doctor visitors have
White-coat hypertension.
2. Masked hypertension
Masked hypertension is for the patient that their blood pressure is only high at certain time
during a day and it’s difficult to find by using office spot measurement. 24 hours
ambulatory blood pressure measurement would be able to ding this kind of hypertension.
It is reported that masked hypertension population taking 10% of the whole population nd
about 40% of the hypertension patients who are having medication therapy. It is very
necessary to have ambulatory blood pressure monitoring for masked hypertension
diagnosis for those hypertension patients who are taking medication.
3. Morning surge hypertension
Morning surge hypertension is for the patients that the average blood pressure during the
2 hours after getting up is more than 135/85mmHg. There are two types-"Only morning
surge" and "Anti-dippers or Non dipper". The “Only Morning Surge” is for the cases that
blood pressure rise suddenly after getting up, and the Anti-dipper or Non-dipper is for the
cases that blood pressure is high at both night and early morning. Both cases are risky
factors for cardiovascular disease. ABPM can help to identify these two types of cases.
4. Nocturnal Hypertension
To diagnosis nocturnal hypertension, people need to measure their blood pressure at
night. A 24ours ambulatory blood pressure monitor is the ideal tool for this kind of
diagnosis.
5. Hypotension
Ambulatory blood pressure monitoring is very useful not only on diagnosis of hypertension
but also hypotension. Especially, the hypotension could cause dizziness or fainting on
elder people who have exhaustion of autonomic nervous when standing, after a meal or
after a bath.
Hypotension is divided into primary hypotension and secondary hypotension. Primary
hypotension is common in women, which usually impact the patient's life quality. However,
only few primary hypotension patients are considered long-term prognosis, because
primary hypotension just leads to few vascular disorders. On the other hand, secondary
hypotension is usually caused by some normal diseases and is accompanied with
dangerous syndromes such as syncope and vertigo, so patients need prevention and
therapeutic measures. In this case, the 24 hours ambulatory blood pressure monitor
would be very helppful.
Besides above circumstances, 24 hours ambulatory monitor is also very helpful on below
cases:
•Childhood hypertension
•Efficacy of anti-hypertensive drug therapy on a 24-hour basis
•Nocturnal hypertension
•Episodic hypertension and/or anxiety disorders
•Resistant hypertension

7
•Changes in diet and daily routine designed to reduce hypertension
•Hypertension in pregnancy
1.2 Brief Introduction of WBP-02A Hospital ABPM
Blood Pressure Monitor with Body Position Information
Hingmed WBP-02A Hospital ABPM is wearable. Comparing traditional ABPM, it’s very
small, light and is worn on people’s arm directly without air tube. The traditional ABPM
used to be attached with a 1 meter longer air tube around patient body. WBP-02A Hospital
has below strength:
1. More comfort for patient as there would be no air tube around patient body.
2. Minimized the ambulatory motion tolerance, improved the measurement consistency.
3. With rechargeable Li battery, ABPM users do not have to cost two AA batteries every
day.
Hingmed ambulatory blood pressure monitor has an outstanding feature that it could
provide the user's body position when taking blood pressure measurement, which could
be very important in clinical research. Most hypertensive diseases, such as dizziness,
nausea, brain death, happened under spirit pressure with body movement. Therefore,
monitoring patient’s blood pressure should not be confined to a calm condition. Blood
pressure measurement under ambulatory environment would more closely reflect patient
normal blood pressure situation. And that would be extremely helpful on clinical diagnosis.
In addition, blood pressure data with body position information can help doctors to make a
good judgment on orthostatic hypertension. Body position hypertension is that some
patient would only have high blood pressure under standing or sitting posture, but normal
at lying posture. Orthostatic hypertension accounts for 4.2% in domestic hypertension
patients and 10% in abroad report. Orthostatic hypertension is characterized by that there
is not hypertension in normal and just being found occasionally or in physical examination.
Diastolic pressure rising-up and large fluctuation would represent in orthostatic
hypertension and the individual could be accompanied by serious palpitation, tiredness,
sleep quickly etc. In blood examination, the plasma rennin activity in orthostatic
hypertension is higher than that of normal people, even than that of general hypertension
patient.
