Measurement of 24 hours arterial blood pressure

Measurement of 24-Hour Arterial Blood Pressure (ABPM) is a comprehensive 24-hour blood pressure monitoring test that enables an objective assessment of blood pressure changes throughout the day and night. During the examination, an automatic portable device is used to measure the patient's blood pressure at regular intervals while they continue their usual daily activities.

Twenty-four-hour monitoring allows the detection of blood pressure fluctuations that often go unnoticed during a single measurement. Therefore, this test is important for identifying both persistent and episodic blood pressure abnormalities.

When Measurement of 24-Hour Arterial Blood Pressure May Be Required:

• to assess blood pressure fluctuations throughout the day,
• to confirm or clarify a possible diagnosis of hypertension or hypotension,
• to identify nighttime blood pressure changes,
• to monitor blood pressure variations during treatment,
• to determine the causes of episodic blood pressure elevations,
• to detect so-called “white coat” hypertension.

The examination may also be recommended for individuals experiencing headaches, dizziness, palpitations, changes in heart rhythm, or other symptoms related to the cardiovascular system.

How the Examination Is Performed

1. Device Placement

• A healthcare professional places a cuff on the upper arm and attaches the recording device to a belt or shoulder strap.

2. 24-Hour Monitoring

• During the day, measurements are typically taken every 15-30 minutes.
• During the night, the device measures blood pressure every 30-60 minutes.

The patient can normally continue working, walking, and sleeping, as the device does not interfere significantly with everyday activities.

3. Patient Diary

The patient may record periods of activity, sleep, symptoms, and medication use. This information helps the physician accurately interpret the measurements.

4. Data Analysis

After 24 hours, the device is removed, and the collected data are transferred to a system where a physician analyzes average blood pressure values, fluctuations, and nighttime blood pressure patterns.

What the 24-Hour Blood Pressure Measurement Reveals

The examination provides information about:

• average 24-hour, daytime, and nighttime blood pressure values,
• the magnitude of blood pressure fluctuations,
• nighttime blood pressure reduction or its absence,
• possible sudden increases or decreases in blood pressure,
• causes of episodic blood pressure elevations related to physical activity or emotional states.

This information helps provide a more accurate understanding of the condition of the cardiovascular system.
