  • monitoring a subject by;

    receiving a first electronic signal from a first sensor located at a first body site of a subject; and

    receiving a second electronic signal from a second sensor located at a second body site of a subject, wherein the second body site is different from the first body site;

    using processor equipment for;

    calculating a Lissajous figure based at least in part on the first and second electronic signals;

    identifying at least one feature of the Lissajous figure; and
