Low cost Electronic Instrumentation Solutions for Cardiovascular Parameters Measurement

Cardiovascular activity is one of the primordial physiological phenomena of human life. However, it is subject to many pathologies due to various factors such as: lifestyle, age, diabetes, cholesterol or heredity. As a consequence, there are different kinds of examination and methods used to enable the diagnostic. In this paper cardiovascular parameters are calculated due to the acquisition of simultaneous electrocardiography (ECG) and photoplethysmography (PPG) signals and the high limb peripheral arterial stiffness is evaluated by the calculation of the Pulse Wave Velocity (PWV) parameter. Those measurements are performed by two different low-cost systems based on Arduino board. The acquired waveforms form each device prototype present a satisfactory result, and the cardiovascular parameters are in the range of the value found in the literature. The developed prototype devices could easily be used for engineering educational purposes, hobby or first steps research.
