Relationship between Seismocardiogram and Echocardiogram for Events in the Cardiac Cycle
Abstract
Seismocardiography (SCG) is a noninvasive method to record ultralow-frequency cardiac vibrations from the chest wall using an accelerometer. This research evaluated the relationship between SCG and echocardiography (Echo); 39 subjects had simultaneous SCG and Echo, 28 were normals and 11 had dilated cardiomyopathy. Ten SCG points were compared with their corresponding systolic and diastolic Echo points. The mean absolute difference between SCG and Echo for 5 systolic points was 7.6 ms and 6.8 ms for the 5 diastolic points. Two SCG systolic points showed increased divergence from the Echo points in subjects with cardiomyopathy. Both methods showed approximately equal ability to distinguish longer cardiac time intervals among abnormals compared with normals. Intrasubject variability was lower in the SCG than Echo. The consistency between SCG and Echo points indicates that they are equally accurate in measuring cardiac time intervals.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
