• Patent extends HeartBeam's ECG hardware platform with multi-modal sensing capabilities
  • Acoustic sensors enable HeartBeam’s device to function as a "digital stethoscope" to assess heart valve function
  • Thoracic impedance capability opens the door to heart failure monitoring without a surgical procedure
  • HeartBeam now holds 26 issued patents worldwide, reflecting continued investment in building a durable IP moat around its platform

HeartBeam, Inc. (NASDAQ:BEAT), a medical technology company focused on transforming cardiac care by providing powerful cardiac insights, today announced the allowance of a new U.S. patent that significantly expands the capabilities of its credit card-sized, cable-free ECG device. The patent covers the integration of acoustic sensing and thoracic impedance measurement into the existing ECG hardware platform, supporting future applications in structural heart disease and heart failure monitoring.

The new capabilities protected by the patent are promising for enabling earlier identification of structural irregularities in the heart valves and signs of fluid accumulation for heart failure patients without requiring a new form factor. The patent covers the integration of acoustic sensors into the foldable arms of the HeartBeam device, enabling the use of the device as a "digital stethoscope." The sensors are intended to capture the sounds produced when the heart's valves open and close, including the mitral and tricuspid valves, which generate characteristic sounds that reflect how the heart is functioning mechanically and structurally.

The patent also covers thoracic impedance measurement — the ability to inject a small, imperceptible current through the device's finger electrodes and measure the resulting voltage across the chest electrodes to assess how much fluid is present in the chest. HeartBeam's patent protects this capability in the Company’s portable, patient-operated device. Unlike wrist- or finger-worn wearables, HeartBeam's device is used at the chest — the anatomically relevant location for both heart-sound and thoracic-impedance measurement. The allowed patent claims protect this capability as built into HeartBeam's device, positioning the platform where these signals are physiologically accessible.

Heart failure affects nearly 6.7 million adults in the U.S., costs an estimated $30,000 per patient annually, and is one of the leading causes of hospitalization. One of the biggest challenges is that patients accumulate fluid over days before symptoms become severe enough to prompt a hospital visit. Earlier detection of fluid buildup could enable physicians to intervene with diuretics or medication adjustments before hospitalization becomes necessary, improving patient outcomes while reducing healthcare costs.
