Trial Outcomes & Findings for Comparison of the Performance of ICM and CIED in Detecting AF (NCT NCT04940156)

NCT ID: NCT04940156

Last Updated: 2024-10-15

Results Overview

To assess the performance of the Confirm Rx™ ICM and Reveal LINQ™ ICM in detecting clinically significant AF episodes (episodes longer than 6 minutes) in comparison to CIED (gold standard). Confirm Rx and Reveal LINQ™ ICM sensitivity, specificity, positive predictive value and negative predictive value will be calculated for AF episodes longer than 6 minutes.

PRIMARY outcome

Timeframe: During follow-up (6 months)

Population: Data were not collected.

To assess the performance of the Confirm Rx™ ICM and Reveal LINQ™ ICM in detecting clinically significant AF episodes (episodes longer than 6 minutes) in comparison to CIED (gold standard). Confirm Rx and Reveal LINQ™ ICM sensitivity, specificity, positive predictive value and negative predictive value will be calculated for AF episodes longer than 6 minutes.
