The recent advances in multiparametric monitoring of biosignals and management of big data prompt for the development of devices and techniques for the extraction of indicators with physiological relevance. In this context, we have designed and realized a portable electronic system, equipped with simple biomedical sensors, able to synchronously record multiple electrocardiographic (ECG), photoplethysmographic (PPG) and breathing signals, for carrying out a non-invasive monitoring of several cardiovascular parameters. In this work, we show the results of preliminary measurements performed following a specific physiological protocol (i.e., deep breathing with 10 s per cycle). The system allows to monitor specific physiological behaviors, such as the decrease of the R-R interval (increase of the heart rate) during inhalation and the increase of the stroke volume increases during exhalation. The high quality of the ECG/PPG/breath waveforms acquired by our probes, sensors and system allows an improvement in the accuracy of the extraction of noteworthy cardiovascular parameters.
