iRhythm unveils data on real-world performance of Zio Monitor

iRhythm Technologies announced initial research findings on post-market, real-world performance of Zio monitor, its next-generation Zio long-term continuous monitoring (LTCM) patch ECG device, presented at the Heart Rhythm Society’s HRX 2024 meeting. Building on the high performance of its previous generation Zio XT device, the Zio LTCM monitor was designed to be smaller and lighter,3 with a waterproof housing and a new breathable adhesive. For the study, titled “Performance of a Novel Next-Generation Ambulatory ECG Long-Term Patch Monitor: A Multicenter Post-Market Evaluation,” the investigators sought to determine whether these design enhancements translated into improved, post-market real-world device performance compared to its predecessor. The investigators compared U.S. post-market real-world data of iRhythm’s next-generation Zio monitor to its prior generation Zio XT device. The new Zio monitor demonstrated fewer early wear terminations, longer wear duration, and longer analyzable time compared to the prior generation Zio XT device. In unadjusted analyses, there was greater yield of paroxysmal AF and overall arrhythmia detection with Zio monitor.
