Seismocardiogram Records Pressure of the Heart Ventricles on the Ribs

Diagnostic tools to indentify cardiac pathologies are based on measurements of the electrical (electrocardiography, noninvasive electrocardiographic imaging) and mechanical (ultrasound and magnetic resonance imaging (MRI)) activity of the heart. However, unlike electrocardiography, imaging of mechanical deformations in the ventricular walls requires relatively expensive clinical equipment. This problem can be partially solved by using seismocardiography, the mechanical analog of electrocardiography.
