HeartBeam Inc. (NASDAQ: BEAT) announced Wednesday that it has been granted a new U.S. patent covering the integration of acoustic sensing and thoracic impedance measurement into its credit card-sized, cable-free ECG device. The patent expands the company's intellectual property portfolio and paves the way for future applications in structural heart disease and heart failure monitoring.
The new capabilities allow the device to function as a digital stethoscope and assess fluid accumulation in the chest without altering its existing form factor. This means patients could potentially use the portable device at home to detect heart valve abnormalities and fluid congestion earlier, which are critical indicators of worsening heart failure or structural heart issues.
HeartBeam's technology is designed as a multi-modal ambulatory cardiac sensing platform. The company said the patent advances its strategy of developing a comprehensive cardiac monitoring system that can be used outside of medical facilities. The global patent portfolio now includes 26 issued patents covering signal acquisition, ECG synthesis algorithms, diagnostic applications, and device hardware.
The company's core platform technology is the first cable-free device capable of collecting ECG signals in 3D from three non-coplanar directions and synthesizing them into a 12-lead ECG. The HeartBeam System with 12-Lead ECG synthesis software for arrhythmia assessment received FDA clearance in December 2025, with cleared indications for use available at HeartBeam Indications.
This patent expansion is significant for the cardiac monitoring market. Heart failure affects millions of patients worldwide and is a leading cause of hospitalization. Current monitoring often requires bulky equipment or frequent clinic visits. HeartBeam's approach could enable continuous, remote monitoring, potentially reducing hospital readmissions and improving patient outcomes.
