Abstract:

A hydrodynamic model of the systemic circulatory system was mounted on an ultralow-frequency ballistocardiograph ULF-BCG. The relationship between stroke volume and ballistocardiographic amplitude was investigated for different pulse wave velocities. It was found that the amplitude of the displacement ballistocardiogram, as used by Klensch J M minus I J, is strongly correlated to stroke volume however, the relationship is highly dependent on pulse wave velocity. Closer evaluation of the data showed that there is a combination of amplitude measurements that also gives a strong correlation between amplitude and stroke volume but is now independent of pulse wave velocity.
