Personal sensor-system modalities evaluation for simplified electrocardiogram recording in self-care

In this paper we propose a new design of a wearable sensor-system produced in three different sizes for recording anywhere and at anytime three pseudo-orthogonal ECG leads I, II and V2 according to the Mason-Likar system. It looks like a bib and aims to provide any individual with a sensor-system suitably adapted to his/her morphology. Our research goal is to establish for each citizen the most appropriate sensor-system size, which produces ECG signals with a diagnostic content that is closest to that of a standard ECG. In order to evaluate the possible automation of this selection process, we performed a series of experiments on eight healthy volunteers and we present the results of 280 ECG comparisons in terms of correlation, RMS values, as well as changes in diagnosis probability and of selected ECG measurements.
