1. Apparatus for the diagnostic display of a motion signal;

  • characterizing ventricular wall motion of a patient'"'"'s heart;

    from cardiac induced compression waves detected at the surface of said patient'"'"'s body;

    to a diagnostician comprising;

    compression wave monitoring means, responsive to compression waves at the surface of said patient'"'"'s body, for generating a plurality of compression wave signals corresponding to said ventricular wall motion;

    selecting means for detecting the systolic time interval of normal sinus beats of said patient'"'"'s heart, and for generating a data collection window interval during such systolic time interval;

    means for averaging said compression wave signals collected during said data collection window intervals; and

    for generating a composite wave form from said collected compression wave signals.display means for presenting a representation of said composite waveform to said diagnostician.
