Implantable heart rhythm recording device

An implantable loor recorder (ILR) is a way of capturing the heart rhythm at the time of symptoms or episodes which are happening infrequently enough that they are difficult to record with ambulatory heart rhythm recording devices (i.e. “wearable” ECG recording which usually last for up to 2 weeks).

The ILR is nowadays a very small device which can be injected under the skin using local anaesthetic and can capture episodes of a fast or slow heart beat or when the individual has their symptoms and presses a button to activate a recording.

The battery life for an ILR is in the region of 3 years but it can be removed sooner or even left in place for longer depending upon individual preference.
