Testing Procedure


The blood pressure monitor consists of a blood pressure cuff worn on your arm (usually the arm of your non-dominant hand) which is attached to a monitor worn around your waist (approximately the size of a portable casette tape player). The blood pressure monitor will not display your blood pressure readings throughout the 24 hour period, but are stored on the recording device, and then analysed by a qualified technician and cardiologist the following day.


When the monitor is taking a reading, it will beep once to prompt you to keep your arm still and relaxed. You will then feel the blood pressure cuff tighten on your arm, and then slowly release. Your arm must remain still and relaxed even when the cuff is deflating. Once the pressure in the cuff has been released, you can continue to use your arm as per normal. If there is any movement in your arm while the monitor is taking a reading, the monitor will automatically repeat the measurement. The technician will give you a demonstration of what to expect before you leave the Heart Centre.
