## Resource

How an ILR Works An ILR is a matchstick-sized device implanted under the skin of the chest, usually under local anaesthetic in a brief outpatient procedure. Once in place, it continuously monitors the heart’s electrical activity, storing recordings of any abnormal events it detects automatically or when triggered by the patient using a handheld activator. Modern ILRs have: Automatic arrhythmia detection algorithms Wireless home monitoring (transmitting daily summaries to the cardiology team) Battery life of 2–4 years MRI-compatibility in most cases When to Consider an ILR An ILR may be recommended if you: Have unexplained syncope with inconclusive standard tests Have had a cryptogenic stroke, TIA, or TGA, where AF is suspected but not proven Have infrequent but concerning palpitations that evade short-term monitoring Have suspected intermittent AV block or sinus pauses Full blog article
