The clinical application of ballistocardiography to the study of heart disease has to date been elusive. Recent studies with high-frequency (acceleration) direct body ballistocardiography interpreted in terms of the second derivative of the carotid pulse and its own further differential have sharply delineated and reoriented the component forces of early (HI) and later (IJK) systolic phases.
The theory proposed is that the normal "synergic" heart contracts with optimal acceleration maintaining the integrity of the HI and J waves, whereas acceleration of the "asynergic" heart is diminished even in the presence of minimal focal injury dominantly reflected in the diminished early
