A compact electric potential sensor array for the acquisition and reconstruction of the 7-lead electrocardiogram without electrical charge contact with the skin

connections to the arms and legs. These use a ‘long baseline’ for the voltage
reference potential which in the case of precordial ECG leads is provided using
aWilson central terminal (WCT) wiring configuration. The aims of this project
were (a) to construct compact, non-invasive surface ECG sensor arrays which
would operate without the need for a WCT reference, (b) to obtain high quality
precordial ECGs showing fine differences inECGdetail between small adjacent
areas of the chest and (c) to reconstruct, from a compact array of four sensors,
ECGs which closelymatch to the conventional 7-lead ECG system, but without
the need for multiple wires and long baselines. In this paper, we describe two
sensor array configurations which have been constructed using electric potential
sensors (EPSs). We show high quality precordial ECGs obtained from small
areas of the surface of the chest and show the different angular vectors (leads)
in the frontal cardiac plane constructed using signals from the array elements.
We suggest that these ECG arrays, which are simple to apply, should prove to
be a valuable tool in providing useful information about the state of the heart.
