to conventional methods. One study reported a diagnosis in 73% of subjects using ILRs, against 21% with conventional strategies, while also proving to be more cost-effective despite higher initial costs. Another study focused on ILR use for detecting asymptomatic atrial fibrillation in individuals aged 70-90 years with additional stroke risk factors. This trial found that ILR screening led to a threefold increase in atrial fibrillation detection and anticoagulation initiation. However, it did not show a significant reduction in the risk of stroke or systemic arterial embolism, indicating that not all screen-detected atrial fibrillation might warrant anticoagulation treatment.

275:. A small incision (about 3–4 cm or 1.5 inches) is made just lateral to the sternum below the nipple line, usually on the patient's left side. A pocket is created under the skin, and the ILR is placed in the pocket. Patients can go home the day of the procedure with few restrictions on activities. Bruising and discomfort in the implant area may persist for several weeks.

pushing a button when they notice symptoms such as skipped beats, lightheadedness or dizziness. The ILR records by "freezing" the electrical information preceding, during and after the symptoms in the format of an electrocardiogram. The technician or physician can download and review the recorded events during an office visit using a special

Recent studies have underscored the diagnostic effectiveness and cost-efficiency of implantable loop recorders (ILRs) in specific patient populations. In patients with unexplained palpitations, especially those with infrequent symptoms, ILRs have shown a significantly higher diagnostic yield compared
