Milestone results formed the basis of HeartBeam’s 12-lead ECG synthesis software application submitted to FDA in January 2025

HeartBeam, Inc., (NASDAQ: BEAT), a medical technology company focused on transforming cardiac care by providing powerful personalized insights, today announced that its groundbreaking synthesized 12-lead electrocardiogram (ECG) successfully met the clinical endpoints in the VALID-ECG pivotal study. Thomas Deering, M.D., of Piedmont Heart Institute, presented the data during the just concluded Heart Rhythm Society’s annual conference in San Diego.

The study evaluated the mean difference in ECG intervals and amplitudes between HeartBeam’s synthesized 12-lead ECG and simultaneously collected standard 12-lead ECG that are important in assessing non-life-threatening arrhythmias. Data showed a 93.4% overall diagnostic agreement, indicating that HeartBeam’s synthesized 12-lead ECG can support diagnosis of arrhythmias in a manner consistent with standard 12-lead ECGs.

"This important milestone successfully confirms that our novel technology can deliver diagnostic insights similar to a standard 12-lead ECGs for arrhythmia assessment," said Robert Eno, Chief Executive Officer, HeartBeam. “The ability to deliver 12-lead ECG-like data through a credit card-sized device that patients can use whenever and wherever arrhythmia symptoms occur underscores our long-term vision of bringing advanced cardiac health insights beyond medical facilities to improve patient outcomes.”

HeartBeam’s patented 3D ECG technology captures the heart’s electrical signals in 3 non-coplanar directions and then synthesizes these signals into a 12-lead ECG using a personalized transformation matrix. Data from the VALID-ECG study formed the basis of the FDA application for the 12-lead ECG synthesis software submitted by HeartBeam in January 2025.

The Company plans to initiate commercialization upon receiving FDA clearance for the 12-lead ECG synthesis software. In advance of that, the Company recently commenced an Early Access Program to obtain important feedback on the end-to-end clinical workflow, ensure operational readiness and establish an early adopter funnel in anticipation of US commercialization.

The VALID-ECG pivotal study was a multicenter trial that enrolled 198 patients across five clinical sites in the US, including Allegheny Health Network, Atlanta Heart Specialists, Mount Sinai Hospital, Northwell Health and Piedmont Heart Institute.

About HeartBeam, Inc.

HeartBeam, Inc. (NASDAQ: BEAT) is a medical technology company dedicated to transforming the detection and monitoring of critical cardiac conditions. The Company is creating the first ever cable-free device capable of collecting ECG signals in 3D, from 3 non-co-planar directions, and synthesizing the signals into a 12-lead ECG. This platform technology is designed for portable devices that can be used wherever the patient is to deliver actionable heart intelligence. Physicians will be able to identify cardiac health trends and acute conditions and direct patients to the appropriate care – all outside of a medical facility, thus redefining the future of cardiac health management. HeartBeam’s 3D ECG technology received FDA clearance for arrhythmia assessment in December 2024. The Company holds 14 U.S. and 4 international issued patents related to technology enablement.
