The study uses a monitoring system to measure pressures inside the heart and lungs in a non-invasive way. This monitoring system consists of a handheld electronic device, similar to a smartphone, which will be placed on the chest and a smartwatch to wear on the wrist. Ultimately, the monitoring system will be intended to be used by doctors as a tool to support them when assessing patients with symptoms that may be due to a condition of their heart and/or lungs.

The purpose of this study is to collect data from eight sensors built in the study device (the smartphone and the watch). The data collected from the device, as well as the data collected during your Right Heart Catheterization, will be uploaded in a database. Once all subjects have been enrolled in the study, these data are then used to build the software which will be used in the final monitoring system. The device used in this study is not approved for commercial use and can only be used in clinical investigations.
