Arterial Stiffness as a Tool to Investigate Adherence in Resistant Hypertension

Non-invasive CARDIS Technology Demonstrator (CTD) device is a 2 x 6 beam laser Doppler vibrometer (LDV) for non-contact measurement of skin vibrations caused by underlying cardiac action. The CTD device is a split device with a master device and a slave device, which are connected to a data acquisition rack, which again is connected to a computer for signal processing, data presentation and data logging.
