Grant Neitzell subsequently provides a comprehensive review of innovation in ICMs, culminating in the LINQ™ series featuring AI-driven enhancements via AccuRhythm™, highlighting the diagnostic accuracy achieved.
In this on-demand version of the educational webinar, Dr Luca Santini (Rome, IT) and Prof Klaus Witte (Leeds, UK) join Alphons Vincent (Medtronic) and Grant Neitzell (architect of the Reveal LINQ system, Medtronic), to explore the critical importance of sensitivity and specificity in Insertable Cardiac Monitors (ICMs). The faculty consider how reducing false positives impacts sensitivity, why balancing these factors is essential, and what real-world data reveals about achieving clinical accuracy. The programme also highlights opportunities to streamline clinical workflows and minimise patient follow-ups.
Prof Witte discusses the impact on stroke patients, supported by findings from his recent poster presented at EHRA 2025, while Dr Santini presents real-life case studies, illustrating broader implications for various patient populations.
Learning Objectives
- The value of sensitivity in improved patient outcome
- The value of specificity in improved clinical workflow
- The impact of sensitivity on stroke and syncope patients
- How not all ICMs are the same and how specificity and sensitivity, are differentiating the ICM market
This programme has particular educational value for:
- Electrophysiologists
- Cardiac physiologists
- General cardiologists
- Rhythmologists
- Neurologists
- All other healthcare professionals involved in arrhythmia management

Part 3
How ICM Sensitivity and Specificity Impact Clinical Decision Making – Klaus Witte
Prof Klaus Witte explores ICMs’ role for diagnosing unexplained syncope and cryptogenic stroke, offering superior diagnostic yield compared to conventional monitoring. He asserts that advances such as AccuRhythm™ AI improve specificity by reducing false positives – particularly for AF and pause events – while maintaining high sensitivity, which is critical for capturing clinically relevant arrhythmias.
Part 4
How ICM Sensitivity and Specificity Impact Clinical Decision Making – Luca Santini
Dr Luca Santini notes that ICMs are guideline-recommended for evaluating unexplained syncope and bradyarrhythmias, offering superior diagnostic yield in low-frequency or high-risk cases. He concludes that the current application of AI for loop recorders supports reducing false alerts, while maintaining high sensitivity and ensure patients’ safety.
Part 5
Panel Discussion and Summary
Alphons Vincent leads a panel discussion and audience Q&A, covering themes including clinical interpretation of AI-optimized ICM data, particularly around alert burden, AF thresholds, and false positives; diagnostic accuracy and sensitivity trade-offs, including concerns about missed or over-detected events; and practical integration into workflows, such as decision-making in unexplained syncope or silent AF cases.
