Description Cardiovascular diseases (CVD) are the leading cause of mortality worldwide, accounting for approximately 17.9 million deaths per year or 32% of total annual deaths. Early diagnosis and treatment of CVD can drastically reduce the likelihood of premature mortality and ensure a normal life for those strongly related to Pulse Wave Velocity (PWV). Pulse Wave Velocity (PWV) represents the speed of pressure wave propagation within arteries and is usually assessed between the carotid and femoral sites. Specifically, it is calculated as the ratio of the distance between the two sites to the time elapsed to travel that length. PWV estimation is performed with instruments based mainly on applanation tonometry, but the high cost severely limits their use in the clinical setting.
The aim of this thesis is the development of a wearable device for carotid-femoral PWV estimation. This study's challenge is using electrodes as sensing elements to detect the propagation of the wave by stimulating the tissue under examination and reading its changes due to the wave's passage.
The first part of the thesis will focus on studying the state of the art and analyzing the feasibility of this approach. Secondly, we will continue with the acquisition, algorithmic development, and signal processing. Finally, a prototype of such a device will be designed.
