NEW YORK & SEOUL--(BUSINESS WIRE)--AccurKardia, Inc., an ECG-led diagnostics software company, and Wellysis, a digital healthcare company and developer of the S-Patch wearable ECG monitor, today announced a multi-year agreement under which AccurKardia’s AccurECG 2.0 will power the analytics behind Wellysis’ turnkey cardiac monitoring offering in the U.S. The agreement, which was signed last week in Seoul, is the latest between the two companies.

Under the agreement, Wellysis’ S-Patch wearable device will be paired with AccurKardia’s automated ECG analytics and reporting platform to deliver a complete, clinician-ready solution for Holter, extended Holter, and mobile cardiac telemetry workflows.

The combined offering gives U.S. cardiology and general medicine practices access to a seamless, end-to-end monitoring solution that integrates hardware, analytics and reporting into a single workflow delivering patient reports faster to improve outcomes. The agreement between AccurKardia and Wellysis follows the integration of the companies’ platforms in April 2025, with AccurKardia becoming an approved vendor to Wellysis in June 2025.

“This partnership demonstrates the power of close collaboration between two teams committed to improving cardiac care,” said Juan C. Jimenez, co-founder and CEO of AccurKardia. “We are excited to serve as the analytics engine powering Wellysis’ offering in the U.S. By combining the S-Patch with our automated, FDA-cleared ECG analytics platform, we are giving clinicians a complete, ready-to-use monitoring solution that fits directly into their workflow.
