iRhythm Technologies Inc. Expands into Japan with AI-Powered ECG Monitoring

iRhythm Technologies, Inc., a prominent health care equipment and supplies company based in San Francisco, has recently launched its Zio® Long-Term Continuous Monitoring Service in Japan. This service, marketed as the Zio ECG Recording and Analysis System, represents a significant advancement in AI-powered arrhythmia detection. The introduction of this service is timely, given the increasing demand for early and accurate detection of arrhythmias in Japan, which is the world’s second-largest market for ambulatory cardiac monitoring.

The Zio® system offers a superior monitoring duration of up to 14 days, significantly outpacing existing options in Japan, such as Holter monitors (24-48 hours) and other patches (7 days). This extended monitoring capability is crucial for capturing intermittent arrhythmias that shorter-duration devices might miss. The system has received PMDA approval for its AI algorithm, which can detect 13 types of arrhythmias, showcasing impressive metrics with 99% patient compliance and 99% analysis accuracy.
