ABPM (24h AMBULATORY BLOOD PRESSURE MEASUREMENT)
This test is performed using devices consisting of a cuff and a central unit. ABPM devices have the ability to automatically perform multiple blood pressure measurements at regular intervals during day and night.
The central unit records BP measurements throught the day and subsequently the doctor evaluates it via specialized software. In particular extreme measurements and average blood pressure (24-hour average greater than 135/85 mmHg makes the diagnosis of hypertension) are evaluated.
This test is usually requested by the cardiologist either in the context of hypertension diagnosis or for monitoring therapeutic effects in patients already receiving medication. ABPM may also be used to rule out the diagnosis of white-coat hypertension (ie high blood pressure levels due to the presence of a health care professiona during the measurement). No special preparation is required to perform this exam.
