Report Scope of Implantable Loop Recorders Market

Implantable Loop Recorders Market By Activation Insights

The automatic recorders segment held the largest market share of 60.6% in 2024 and is anticipated to grow at the fastest CAGR over the forecast period. Automatic recorders are devices designed to continuously monitor and record the electrical activity of the heart without requiring manual intervention. These devices are typically used for long-term monitoring of patients with arrhythmias, ensuring consistent and accurate data collection over extended periods. Their ability to autonomously trigger recording during abnormal heart rhythms makes them crucial in detecting intermittent arrhythmias. On October 2023, a study published in EP Europace evaluated the use of implantable loop recorders (ILRs) for continuous rhythm monitoring in patients with systemic right ventricles following atrial switch repair. Out of 24 patients, significant arrhythmias were detected in 63% of the cohort, leading to changes in medication and device therapy recommendations.

The manual recorders segment is expected to grow at a significant rate during the forecast period. Manual recorders require healthcare professionals to initiate and manage the data collection process. These devices are commonly used in clinical settings where more direct, temporary heart monitoring is needed. They offer flexibility but may not provide the continuous monitoring capabilities of automatic recorders, making them more suitable for short-term diagnostic use. In January 2024, an article in EP Europace evaluated an AI-based ILR-ECG Analyzer for improving the diagnostic accuracy of insertable cardiac monitors (ICM), which capture episodes activated manually by patients during symptomatic events. The algorithm effectively reclassified many abnormal diagnoses, potentially easing the clinical workload of reviewing ICM events.
