24-hour ambulatory blood pressure monitoring (ABPM / MAPA)
ABPM records blood pressure over 24 hours, during everyday activities and sleep. It helps assess how readings vary throughout the day and night.
What is it used for?
It may be recommended to clarify a diagnosis of high blood pressure, monitor blood pressure and assess the response to treatment, according to the medical assessment.
How is it performed?
A cuff is fitted around the upper arm and connected to a small portable monitor. The device takes automatic readings at regular intervals over 24 hours. The cuff may feel temporarily tight as it inflates.
During the test
Follow the instructions provided on caring for the device and recording your activities. The information collected is then reviewed and interpreted by the doctor.
ECG — Electrocardiogram
An electrocardiogram records the electrical activity of the heart. It assesses the heart rate and rhythm at the time of the test.
What is it used for?
It can help identify heart rhythm changes and assess how the heart is working, taking account of symptoms, medical history and the reason for the test.
How is it performed?
For a resting ECG, small electrodes are attached to the skin and connected to the equipment. You lie still during the recording, which usually takes a few minutes.
What should you know?
The test is non-invasive and generally painless. The results should be interpreted by the doctor alongside the rest of your clinical information. Some situations may require further tests.
24-hour Holter — Heart rhythm monitoring
A Holter monitor continuously records the electrical activity of the heart for 24 hours, including during everyday activities and sleep.
What is it used for?
It can help detect intermittent heart rhythm changes that do not appear during a short ECG. It may also be used to monitor arrhythmias and assess treatment, as recommended by the doctor.
How is it performed?
Electrodes are attached to the chest and connected to a small portable recorder that you wear throughout the test.
During the test
Follow the instructions provided to protect the equipment and record any symptoms and activities. Afterwards, the recording is analysed to relate any heart rhythm changes to what happened during the day.
