About

Seismocardiography (SCG) measures the thoracic vibrations caused by the cardiac contraction and ejection of blood into the great vessels. Current smartphones with gyroscopes and accelerometers can measure these vibrations. Based on these components we measure and quantify the cardiac kinetic energy (kinocardiography) in order to differentiate dyspnea of cardiac origin from dyspnea of other origin. The study is conducted in an emergency service where a smartphone performs the measurement during 3 minutes. The results of the kinocardiography-based classification are then compared to the final diagnosis made by a physician. Currently, 235 patients have been included in the clinical study since May 2022. This rapid and non-invasive measurement allows the aid-to-diagnosis of heart failure without being influenced by other factors like the renal function for example that can be NT-pro BNP blood marker.
