7 terms

electrocardiography medical

"a healthcare information technology (“HIT”) company focused on advancing electrocardiography (“ECG” or “EKG”)"

Electrocardiography is a medical test that records the heart’s electrical signals using sensors on the skin, producing a tracing that shows heart rhythm and timing. Investors should care because these readings are routinely used to assess the safety and effectiveness of drugs, medical devices, and treatments—like checking a building’s wiring for faults—so abnormal results can affect clinical trial outcomes, regulatory approval, and product marketability.

electrocardiogram medical

"titled “Electrocardiogram-Based Assessment of Diastolic Function.”"

An electrocardiogram (ECG or EKG) is a simple, noninvasive test that records the heart’s electrical signals through sensors on the skin and displays them as a waveform showing heart rate and rhythm. For investors, ECGs are important because they are a primary tool for diagnosing heart conditions, monitoring safety and effectiveness in clinical trials, and driving demand for medical devices and services—like a dashboard gauge revealing whether a car’s engine is healthy.

diastolic function medical

"Electrocardiogram-Based Assessment of Diastolic Function."

Diastolic function is the heart’s ability to relax and fill with blood between beats, like a balloon that must loosen to take in air before the next squeeze. It matters to investors because impaired filling can drive demand for drugs, devices, hospital care and long‑term treatment costs, influence regulatory reviews and trial outcomes, and affect productivity and insurance risk — all of which can change a company’s revenues and valuations.

echocardiogram medical

"estimate echocardiogram parameters indicative of diastolic function using ECG data"

An echocardiogram is a noninvasive ultrasound scan that creates a moving picture of the heart’s chambers, valves and blood flow—like a live camera or sonar for the heart. Investors track echocardiograms because results influence clinical diagnoses, drug and device trial outcomes, regulatory decisions and patient treatment plans, all of which can affect a healthcare company’s revenues, liability risk and market outlook.

machine learning technical

"The patented technology uses machine learning models, trained on ECG and echocardiography data"

Machine learning is a set of computer programs that learn patterns from large amounts of data and improve their predictions or decisions over time, like a recipe that gets better each time it’s adjusted based on taste tests. For investors it matters because these systems can speed up analysis, spot trends or risks humans might miss, automate routine work, and potentially create competitive advantages or cost savings that affect a company’s performance.

View in glossary

artificial intelligence technical

"through the integration of artificial intelligence (“AI”), today announced the grant"

Artificial intelligence is the ability of computers and machines to perform tasks that typically require human thinking, such as understanding language, recognizing patterns, or making decisions. For investors, it matters because AI can enhance efficiency, uncover new insights, and enable smarter strategies, potentially impacting the value and performance of companies that develop or utilize this technology.

unitary patent regulatory

"The patent took effect as a Unitary Patent on April 29, 2026"

A unitary patent is a single patent right that provides uniform protection across multiple participating countries in a region, replacing the need to maintain separate national patents in each country. For investors, it matters because it can reduce the cost and complexity of protecting and enforcing key technologies across markets, affecting a company’s competitive moat, licensing revenue potential, and the scale and cost of patent litigation—similar to holding one passport instead of many.

Patent covers machine-learning models that use ECG data to estimate echocardiogram parameters indicative of diastolic function

Southlake, TX, June 11, 2026 (GLOBE NEWSWIRE) -- HeartSciences Inc. (Nasdaq: HSCS; HSCSW) (“HeartSciences” or the “Company”), a healthcare information technology (“HIT”) company focused on advancing electrocardiography (“ECG” or “EKG”) through the integration of artificial intelligence (“AI”), today announced the grant by the European Patent Office (EPO) of European Patent No. EP4252651, titled “Electrocardiogram-Based Assessment of Diastolic Function.” The patent covers machine-learning models and methods for computing quantitative estimates of echocardiogram parameters indicative of diastolic function using ECG data and patient demographic parameters.

“Securing European patent protection for ECG-based assessment of diastolic function is an important expansion of our AI-ECG intellectual property portfolio,” said Andrew Simpson, CEO of HeartSciences. “Diastolic dysfunction is an important indicator of cardiac disease that has traditionally required imaging-based assessment. This grant further reinforces our strategy of transforming the ECG into a far more valuable front-line cardiac screening tool and underlines the considerable embedded IP value in HeartSciences. We believe the breadth of our patent portfolio provides a meaningful commercial advantage as the field of AI-ECG continues to expand.”

The patented technology uses machine learning models, trained on ECG and echocardiography data, to estimate echocardiogram parameters indicative of diastolic function directly from a patient’s ECG.

The patent took effect as a Unitary Patent on April 29, 2026, and provides coverage in 19 European countries: Austria, Belgium, Bulgaria, Croatia, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Romania, Slovenia and Sweden. With this grant, HeartSciences’ intellectual property portfolio now includes more than 45 granted patents.
