24-hr ABPM Patterns

1. Normal Blood Pressure

Blood pressure fluctuates over 24 hours within an optimum range (grey band) as shown in the diagram, forming a unique blood pressure pattern. At night when you sleep, the blood pressure should dip 10 - 15 % of your average day BP.

Normal Blood Pressure


2. White Coat Hypertension

Generally, the BP falls within the normal range, except when the BP is being measured in the doctor’s clinic, where it is elevated.

About 20% - 25% of hypertension cases are White Coat Hypertension.

3. Borderline Hypertension

One moment your readings are normal, whereas other times, they are high. You could be wondering what is wrong, you or the measuring device.

Chances are that you could be borderline hypertensive, where your BP is hovering between normal and high.

Bring your 24-hour BP pattern to your doctor and he will decide if you should be treated after evaluating your other risk factors. Individualized treatment may be started after careful evaluation of other cardiovascular risk factors, and include lifestyle changes and close monitoring.

Borderline Hypertension


4. Nocturnal Hypertension

With this pattern, the BP readings are normal during the daytime, and becomes high when the person goes to sleep at night. Many stroke victims have this kind of BP pattern.

You may never know you have this BP pattern unless you have your 24-hour BP pattern tracked, especially when you sleep. 

Nocturnal Hypertension


5. Systolic and Diastolic High with Night-time Dip

Both the systolic and diastolic BP are high but you have not lost your circadian rhythm, where your BP dips by 10% - 15% while you are asleep.

Your BP can be restored with the appropriate long-acting drug at adequate dosages.

Systolic and Diastolic High with Night-time Dip


6. Systolic and Diastolic High without Night-time Dip (Non-Dipper)

Both the systolic and diastolic BP are high; however, this pattern does not have the 10% - 15% dip during the night.

Your doctor will aim to reduce both your systolic and diastolic BP and recommend a change in lifestyle and an additional drug at nighttime could help to restore your circadian rhythm.

Systolic and Diastolic High without Night-time Dip


7. Isolated Systolic Hypertension

This pattern clearly shows that the systolic BP is high, whereas the diastolic BP is normal. Most elderly and people with hardened arteries have this BP pattern.

Your doctor will aim to reduce your systolic BP while maintaining the diastolic BP.

Isolated Systolic Hypertension


8. Isolated Diastolic Hypertension

This BP pattern is characterised by a normal systolic BP and a raised diastolic BP.

The causes of this are many and varied. Your doctor will assess the underlying causes and your overall condition before recommending treatment.

Isolated Diastolic Hypertension


9. White Coat Normal Tension

It is also known as Masked Hypertension. It refers to patients who have normal clinic BP when they are seeing a doctor, but their ABPM patterns are abnormal and can be any of the abnormal patterns from no.3 to 8 as mentioned.
