23 May 2021 / 4:26 pm

What is it ?

A small device that is inserted under the skin (usually over the left shoulder or armpit) to continuously monitor your heart rhythm An ILR is particularly helpful for people who have episodes of blackout or palpitation. The device continuously monitors your heart rhythm and can record and send through any abnormal rhythms.


How is it performed ?

Under local anaesthetic a small incision is made and the device injected under the skin. The incision is then closed with steristrips. Antibiotics are given to minimise any infection risk.

How long does it take ?

About 15 minutes.

Are there any risks ?

There is a small risk of bleeding and a risk of infection.(less than 1 in 100).

What happens next ?

The wound will need to be kept dry for a few days. You will be given an activator device and a home monitor. If you have any of your typical symptoms (e.g. collapse) then you should press the button on the activator over your ILR. This will store the heart rhythm in the ILR memory. The device will also automatically send through any abnormal heart rhythms via the internet. You will be given the contact details of you cardiology department who will be able to download the recording. The device battery lasts up to 3 years at which point the device can be removed.
