The development of sensors recording peripheral biosignals and algorithms evaluating these signals plays an important role in future prevention of cardiovascular diseases. The combination of the electrocardiogram and simultaneously registered pulse waves at dierent peripheral sites offers the possibility to determine the pulse wave velocity, which can be used as a cardiovascular risk indicator. Therefor an ECG Modul and a Pulse Wave Modul have been developed. The modules work autonomously and provide on the one hand information about the start of the cardiac cycle, the ejection of the blood and thus the emission of the pulse wave and on the other hand information about the point in time of the arrival of the observed pulse wave at the peripheral sites. These information are extracted by reliable and robust algorithms running on a digital signal processor, which is used as the computational unit and to control the whole process of the determination of the pulse wave velocity. In the future the recorded signals shall be used as an input for mathematical models for the derivation of the aortic pulse wave and hence the aortic pulse wave velocity to improve cardiovascular risk assessment.
