抄録

1) The Ballistocardiograms of 27 normal adults were recorded by Yoneyama's table type vectorballistocardiograph.
2) The mean, standard deviation and range for the QH time, QI time and QJ time obtained from the longitudinal ballistocardiogram were given.
3) The mean, standard deviation and range of coefficiency of variants for the QH time, QI time, QJ time, IJ amplitude and HI amplitude were given.
4) The exspiratory/inspiratory ratio of the HI-and IJ amplitude were given.
5) Results of spatial vectors of H wave, I wave and J wave in frontal plane were discussed.
