title: On the classification of ballistocardiograms.
abstract: An improvement of Brown's classification is described... The new classification reflects the amplitude and time-relation changes of the Bcg. A method for estimating the mean values of Bcg elements, based on the principle of calculation of all corresponding values during the complete 2-3 respiratory cycles is described
