HeartKey by B-Secur is a suite of powerful ECG algorithms and analytics providing high levels of clinical accuracy and efficiency through enhanced signal clarity and reduced ECG signal noise. It delivers FDA-cleared health data with actionable wellness insights. HeartKey's ECG algorithms and analytics for medical and consumer applications can run on-device or via the cloud through a Web API. It enhances existing platforms and devices, such as wearables and Holter monitors, delivering cleaner data and improving remote monitoring. HeartKey measures the variation in time between each heartbeat, providing insights into cardiac and physical health. It analyzes incoming ECG to determine if an arrhythmia may be present and continuously monitors ECG to measure the current stress state. HeartKey's User ID personalizes and protects physiological data, enhancing customer analytics and reducing data corruption risk. The intelligent and adaptive signal conditioning technology enables high accuracy ECG detection on both dry and wet electrodes in real time. HeartKey calculates heart rate by localizing the QRS complex and measuring the distance between each QRS complex. Developed after 15 years of research into ECG technology, HeartKey has a continuously developing ECG and vital signs roadmap. It is validated against industry gold standards and delivers consistent high performance on challenging data. HeartKey offers cloud-based or on-device software options for flexibility and seamless integration into a wide range of existing platforms and devices.
