24-HOUR AMBULATORY BLOOD PRESSURE MONITORING
Ambulatory Blood Pressure Monitoring (ABPM) is a painless non-invasive method to obtain blood pressure (BP) recordings over a 24-hour period usually requested by your cardiologist in Singapore and around the world. It involves wearing a small arm cuff around the non-dominant arm, which is then attached to a small monitoring device worn on a belt fastened around the waist. The arm cuff will automatically inflate at regular intervals every 15 – 30 minutes throughout the day and hourly after 11 pm. The readings can then be used to determine whether the person requires medication for high blood pressure or if the current medication is having the desired effect.

Now that we know the basics of the Ambulatory Blood Pressure Monitoring (ABPM) cardiac test that is offered by The Harley Street Heart & Vascular Centre. Let’s dive deeper into this.
What is 24-Hour Ambulatory Blood Pressure Monitoring?
24-hour ambulatory blood pressure monitoring is a medical procedure that involves the continuous measurement of blood pressure over a 24-hour period. It is considered to be a more accurate method of measuring blood pressure than traditional office-based measurements since it takes into account the natural fluctuations of blood pressure that occur throughout the day and night. This blood pressure measurement method is important for individuals who may have white-coat hypertension or masked hypertension, meaning their blood pressure is only elevated when measured in a clinical setting.
In fact, this 24-hour monitoring can provide a more accurate representation of your true blood pressure. The monitoring is achieved with a small, portable device that is attached to the patient's arm, which they wear throughout the day and night. The device measures your blood pressure at regular intervals, usually every 15 to 30 minutes, and stores the readings for later analysis. The benefits of this procedure include the ability to diagnose and monitor hypertension with greater precision and the ability to adjust treatment plans based on accurate, around-the-clock measurements. Overall, 24-hour ABPM is a non-invasive and effective method of monitoring blood pressure throughout the day that is increasingly used in clinical practice.
White Coat Hypertension
White coat hypertension refers to a condition where a person's blood pressure is elevated when measured in a medical setting, such as a doctor's office, but is normal outside of that environment. This can be due to the anxiety or stress of the medical setting.
Masked Hypertension
Masked hypertension refers to the opposite situation, where a person's blood pressure readings are normal when measured in a medical setting, but is elevated outside of that environment. This can be due to various factors such as stress at home or work, lack of physical activity, poor diet, or other medical conditions.
Benefits of 24-Hour Ambulatory Blood Pressure Monitoring
One of the most crucial benefits of 24-hour ambulatory blood pressure monitoring is its ability to provide an accurate and comprehensive assessment of an individual's blood pressure patterns. This is because this type of monitoring doesn't just measure a person's blood pressure once; rather, it continuously measures it over a 24-hour period. This allows doctors to better understand how a person's blood pressure changes throughout the day during daily activities, and if any potential cardiovascular risks or diseases are present. Here are some of the benefits of 24-hour ABPM:
More Accurate Assessment of Blood Pressure
ABPM provides a more accurate picture of your blood pressure over the course of a day, including during sleep. This is important because blood pressure can vary throughout the day.
Can Help Diagnose and Manage High Blood Pressure
ABPM can help your doctor diagnose high blood pressure if your blood pressure is normal in the doctor's office but high when you are at home or work. ABPM can also help your doctor determine the best treatment for high blood pressure.
Can Identify White Coat Hypertension
White coat hypertension is a condition in which people have high blood pressure only in the doctor's office. ABPM can help identify people with white coat hypertension so that they can be treated appropriately.
Can Help Assess the Effectiveness of Treatment
ABPM allows your doctor to assess the effectiveness of treatment for high blood pressure. If your blood pressure is still high after treatment, ABPM can help your doctor identify the cause of the high blood pressure and make adjustments to your treatment plan.
Can Help Identify Other Cardiovascular Conditions
ABPM can be used to identify other cardiovascular conditions, such as heart failure and other cardiovascular diseases, sleep apnea, stroke, and kidney disease.
Disadvantages of Ambulatory Blood Pressure Monitoring
While ABPM is a valuable tool for assessing blood pressure, it also has some disadvantages. These include:
Cost
The cost of ABPM in Singapore varies depending on the type of device used and the exact location where the test is performed.
Inconvenience
ABPM can be inconvenient for some people, as it requires you to wear a device on your arm for 24 hours. The device is about the size of a pager and weighs about 10 ounces. You will also need to carry a diary with you to record your activities and any symptoms you experience during the test.
Discomfort
The cuff that is used to measure your blood pressure can be uncomfortable for some people. The cuff is inflated to a pressure that is slightly higher than your systolic blood pressure. This can cause some people to feel pain or discomfort in their arms.
Interference with Daily Activities
ABPM can interfere with your daily activities, as you will need to carry the device with you and record your activities in a diary. You may also find it difficult to sleep with the device on your arm. However, keep in mind that there are no risks involved in ambulatory blood pressure monitoring.
Technical Problems
There is a small risk of technical problems with the ABPM device, such as the cuff not inflating or deflating properly. If this happens, you will need to return the device to your doctor for repairs and the validity of the test might be tampered with.
The 24-Hour Ambulatory Blood Pressure Monitoring Procedure
The 24-hour ambulatory blood pressure monitoring procedure is a way for healthcare professionals to get accurate and reliable readings of a patient's blood pressure over a 24-hour period.
The process involves wearing a small, portable blood pressure monitor which is attached to a belt and connected to a cuff on the patient's arm. Over the course of the 24 hours, the monitor will automatically inflate and take readings at regular intervals throughout the day and night. This way, medical professionals can accurately assess the patient's blood pressure and make any necessary adjustments to medication or lifestyle habits.
Before the monitoring process, patients will typically be given instructions on how to prepare. This may include not drinking caffeine or alcohol for a certain period beforehand, and wearing loose-fitting clothing on the day of the procedure. Patients will also be asked to keep a record of their activities during the monitoring period, such as exercise, meals, and sleep.
Many patients find the monitoring device to be comfortable, as the cuff only inflates briefly and does not cause discomfort throughout the day. However, some may experience slight discomfort due to the device being worn for a prolonged period.
The entire monitoring process usually takes around 24 hours, after which the device is removed and the data is analyzed. Patients should consult with their healthcare provider for more detailed instructions and information prior to undergoing the 24-hour ambulatory blood pressure monitoring procedure.
