iRhythm Technologies (NASDAQ:IRTC) has strengthened the case for its international expansion with new clinical data presented at the Asia Pacific Heart Rhythm Society (APHRS) 2025 annual meeting in Singapore. The study focused on the performance of the Zio long-term continuous monitoring (LTCM) service within an Asian patient population, finding that the system’s arrhythmia detection capabilities remain robust and consistent across ethnic lines. This validation is particularly timely as iRhythm Technologies Inc pursues regulatory milestones and commercial growth in Japan. By demonstrating that its deep-learning algorithms perform effectively for these patients, the company reduces clinical risk and paves the way for broader adoption in the region.
