An Exploratory Clinical Study Non-invasive Monitoring of Cardiac Outputs

A positioning system will move the 1X1 cm Pulsify sensor step-by-step over a marked area of 10x10 cm on the subjects' chest to record a complete 3D data set of the heart. For accurate 3D reconstruction, the ECG and breathing cycle are also recorded during the acquisition using commercially available devices (Bitalino HeartBIT + Respiration Sensor). From the 3D dataset of the heart, the end-systolic and end-diastolic volumes will be extracted automatically to calculate the cardiac output.

A complete 2D and 3D ultrasound data set using a GE Vivid E95 ultrasound machine, version 203 (General Electric Healthcare, Chicago, IL, United States) will be recorded. All data will be processed offline with a specialized software packet (EchoPAC, version 203, General Electric Healthcare, Chicago, IL, United States
