24-hour ambulatory blood pressure monitoring (ABPM) measures your blood pressure automatically every 20-30 minutes throughout a full day and night, providing the most accurate diagnosis of hypertension.
The most reliable way to confirm or exclude high blood pressure. A cuff inflates at intervals through the day and night, providing an accurate average and day-night pattern.
The 24-hour ambulatory blood pressure monitoring service is designed for patients experiencing issues related to blood pressure regulation. During this service, patients will wear a portable blood pressure monitor that automatically takes readings at regular intervals over a 24-hour period. This non-invasive procedure allows for a comprehensive assessment of blood pressure patterns throughout daily activities and during sleep.
Patients can expect a face-to-face consultation before the monitoring begins, where the healthcare provider will explain the process and answer any questions. Once the monitor is fitted, patients will go about their usual routines while the device records their blood pressure data. After the monitoring period, the readings will be analysed to identify any abnormalities, such as hypertension or hypotension, which can aid in diagnosing potential cardiovascular conditions.
This service is crucial for understanding how a patient's blood pressure fluctuates in different environments and situations, providing valuable insights that can guide treatment options and improve overall heart health.
ABPM uses a portable cuff that automatically measures your blood pressure at regular intervals over a full 24-hour period, including during sleep. It gives a much more accurate picture than a single clinic reading.
The fitting takes approximately 15 minutes. A blood pressure cuff is placed on your upper arm and connected to a small monitor worn on your belt or in a pouch.
The cuff inflates less frequently at night (usually once per hour) compared with during the day. Most patients find they get used to it quickly and can sleep normally.

A single clinic reading can be affected by white coat hypertension (anxiety raising your BP in a medical setting) or may miss masked hypertension (normal in clinic but high at home). ABPM captures your true average and reveals day-night patterns that guide treatment decisions.
