Key result
The ballistocardiogram waveform more closely maps to the impedance cardiography (flow) waveform than arterial blood pressure, providing a more accurate estimate of stroke volume.
Why the study?
Does the ballistocardiogram (BCG) waveform more closely map to blood flow (ICG) or blood pressure (ABP) for estimating stroke volume in healthy subjects?

Does the ballistocardiogram (BCG) waveform more closely map to blood flow (ICG) or blood pressure (ABP) for estimating stroke volume in healthy subjects?
The ballistocardiogram is more closely related to blood flow than pressure, suggesting it could be a viable, unobtrusive tool for home monitoring of stroke volume.
Javaid et al. (2016) conducted an observational in Healthy (n=19). Ballistocardiogram (BCG) waveform analysis vs. Impedance cardiography (ICG) and arterial blood pressure (ABP) waveforms was evaluated on Mathematical relationship between the BCG signal and ICG/ABP waveforms for estimating stroke volume. The ballistocardiogram waveform more closely maps to the impedance cardiography (flow) waveform than arterial blood pressure, providing a more accurate estimate of stroke volume.
