Ambulatory Blood Pressure Monitoring (ABPM) – 24-Hour Blood Pressure Holter
Ambulatory Blood Pressure Monitoring (ABPM), also known as a blood pressure Holter test, allows blood pressure to be measured continuously over a full 24-hour period. Unlike a single measurement taken during a clinic visit, this test provides a comprehensive picture of blood pressure behavior throughout the entire day and night.
This examination is particularly important because it has a high predictive value for long-term cardiovascular risk and helps determine whether blood pressure is properly controlled. Continuous monitoring allows physicians to assess the risk of complications such as stroke, heart disease, vascular damage, and kidney dysfunction (O’Brien et al., 2013; Parati et al., 2014).
One of the key advantages of ABPM is the ability to measure blood pressure during sleep. Nighttime blood pressure patterns are considered an important predictor of cardiovascular outcomes and cannot be assessed using routine office measurements (Hermida et al., 2011).
In our clinic, the test is performed using an advanced BIOBEAT device that measures blood pressure without an inflatable cuff. Traditional devices inflate a cuff every 15 minutes, which may cause discomfort and disrupt sleep. The cuff-free technology allows patients to move freely during the day and sleep normally at night while still providing continuous and accurate monitoring.
What is Ambulatory Blood Pressure Monitoring (ABPM)?
ABPM is a diagnostic method that records blood pressure continuously over an extended period, typically 24 hours.
During the test, the device measures both systolic and diastolic blood pressure at regular intervals throughout the day and night. This provides detailed information about blood pressure patterns, including variations related to physical activity, rest, and sleep.
Continuous monitoring offers a more accurate assessment of blood pressure control than isolated measurements performed in the clinic (Parati et al., 2014).
When is a Blood Pressure Holter Test Recommended?
ABPM is useful for identifying blood pressure abnormalities that may not be detected during a single office measurement.
For example, some individuals show normal blood pressure readings at home but elevated readings in a medical setting. Others may show the opposite pattern. Continuous monitoring helps clarify these differences and supports more accurate diagnosis and treatment decisions (O’Brien et al., 2013).
The test is also commonly used to evaluate the effectiveness of antihypertensive medications and determine whether blood pressure remains stable throughout the day and night.
Doctors may recommend a blood pressure Holter test in the following situations:
• When hypertension is suspected but has not yet been definitively diagnosed
• When blood pressure readings vary significantly between different measurements
• When response to blood pressure medication appears insufficient or unstable
• In cases of White Coat Hypertension – elevated blood pressure in medical settings due to anxiety
• In cases of Masked Hypertension – normal blood pressure in the clinic but elevated values at home
• During pregnancy when there is a risk of preeclampsia
• In patients with chronic diseases such as diabetes, cardiovascular disease, or kidney disease
• To evaluate the effectiveness of a newly prescribed medication or dosage adjustment
ABPM also provides valuable information about day-night blood pressure patterns. The relationship between daytime and nighttime blood pressure is an important indicator of cardiovascular risk and can help physicians determine the optimal timing for antihypertensive medications (Hermida et al., 2011).
