Multiparameter monitoring of cardiovascular function

Abstract

We report the preliminary results of a laboratory validation study of a new polycardiographic device for the assessment of cardiovascular function (SensSmartTech). The main principle behind polycardiography is a synchronized measurement of multiple electro- mechanical parameters of the cardiovascular system. The assessment is non-invasive and entails electrocardiography, photoplethysmography, phonography and seismography. The study’s results validate the use of the proposed policardiograph implementation in settings with varying measurement and physiological conditions in both clinical and homecare settings. A simple signal analysis shows that the method is suitable for automated determination of diagnostically relevant features including the heart rhythm, openings and closures of heart valves, heart sounds, and systolic intervals generated as a combination of electrical and mechanical observables.
