Advanced digital stethoscopes for cardiovascular detection

About Eko

Eko Health specializes in advanced medical devices and software that enhance the detection of cardiovascular diseases. Their main product is an electronic digital stethoscope that integrates with AI-powered software to help healthcare professionals identify heart conditions more accurately. The stethoscopes feature Bluetooth connectivity, noise cancellation, and amplification, allowing clinicians to listen wirelessly and clearly. The AI software automatically checks for signs of heart disease, such as atrial fibrillation and heart murmurs, providing reliable results without interrupting the examination process. Eko Health differentiates itself from competitors by combining traditional stethoscope functionality with modern digital enhancements and leveraging a large dataset of real-life heart sounds to train its AI for accurate detection. The company's goal is to improve early detection and timely intervention in heart and lung diseases, ultimately leading to better patient outcomes.
