An ambulatory electrocardiogram (ECG). This can be performed with a Holter Monitor which is a portable device that monitors your heart for rhythm abnormalities during normal activity for an uninterrupted 24 to 48-hour period. During the test, electrodes attached to your chest are connected to a portable recorder - about the size of a matchbox - that's attached to your belt or hung from a shoulder strap. It takes 10 minutes to fit the monitor, the patient then removes the monitor and returns it the next day. The recording is then downloaded onto a computer and analysed by a cardiac physiologist and reported by a cardiologist.
Another form of ambulatory ECG test is an Event Recorder (EVR) which covers 1-2 weeks. You wear a monitor the same as a Holter Monitor and if you have any symptoms, such as dizziness, you press a button on a recording device which saves the recording of your heart rhythm made in the minutes leading up to and during your symptoms. Because you can wear this for a longer period of time it has a higher rate of catching your abnormal rhythm.
Holter and Event Recorder monitoring appointments are available at both Te Whatu Ora, Taranaki New Plymouth and Hāwera hospital sites.
