Implantable Loop Recorder
An ILR is a small, slim computer which is implanted with local anaesthetic under the skin on the left upper chest. It records your heart’s electrical activity. It has a battery that can last up to three years, so it can record your heart rhythm over a long period of time. This is useful if simple tests like an ECG have been unable to determine the cause of your symptoms. The procedure takes a few minutes and you can go home afterwards.
