Key result
BCG significantly matches HF-ECG in evaluating the correspondence between electrical and mechanical cardiac events.
Why the study?
The correspondence between electrical and mechanical events in the heart as measured by ballistocardiogram and high frequency electrocardiogram was not well characterized.
Does the ballistocardiogram (BCG) match the high frequency electro-cardiogram (HF-ECG) in examining the correspondence of electrical and mechanical events in the heart?
Does the ballistocardiogram (BCG) match the high frequency electro-cardiogram (HF-ECG) in examining the correspondence of electrical and mechanical events in the heart?
There is significant matching between ballistocardiogram and high-frequency electrocardiogram signals for examining electrical and mechanical events in the heart.

Supports non-invasive electromechanical assessment; leaves open prospective validation before clinical use.
A ballistocardiogram (BCG) and a high frequency electro-cardiogram (HF-ECG) were recorded from twenty-six volunteer human subjects. Seven of these subjects exhibited abnormal patterns in one (or both) of these signals. Significant matching was found when these signals were used to examine the correspondence of electrical and mechanical events in the heart.
