1. A system, comprising:

  • a curve generator adapted to generate first and second regional displacement curves based on magnitudes of cardiac regional wall displacement over a cardiac cycle length interval for first and second cardiac regions, respectively;

    a curve offset module, coupled to the curve generator, to provide a common magnitude reference for the first and second regional wall displacement curves;

    a curve averager, coupled to the curve offset module, to average each of the first and second regional displacement curves over a predetermined number of cardiac cycles;

    a curve smoothing module, coupled to the curve averager, to smooth the averaged first and second regional displacement curves; and

    a phase computer coupled to the curve smoothing module, the phase computer adapted to compute a relative phase representing a phase relationship between the first and second regional displacement curves based on a frequency analysis, the relative phase indicative of a cardiac wall motion asynchrony.
