AuscultechDx LLC is a medtech startup addressing the development of a smartphone stethoscope and cloud-based storage and real-time diagnostics. The first diagnostic capability to be offered is identification of innocent Still's murmur in children. Principals of the firm have developed an accurate segmentation algorithm to locate the first and the second heart sounds. Once these sounds were identified, Auscultech Dx extracted signal features specific to Still's murmur. Subsequently, machine learning-based classifiers, artificial neural network and support vector machine, were used to identify Still's murmur. With some million children see a pediatric cardiologist for innocent heart murmur per year in the US alone, StethAid empowers pediatricians to analyze murmurs accurately using their smartphone. Fewer unnecessary pediatric cardiologist referrals means healthcare cost savings and less anxiety to families.
