Key result
Portable electromagnetic ballistocardiography detects distinct HIJK complex abnormalities in hypertensive and coronary heart disease.
Why the study?
A practical, easily adaptable method of ballistocardiography for routine office use was needed to study body movements in normal and diseased subjects.
Observational (n=100)
Answers are grounded in this paper and cite their sources.
A practical method of ballistocardiography, easily adaptable to routine office use, is described. The instrument utilized is a portable electromagnetic ballistocardiograph which records the body movements directly. One hundred normal subjects of all ages were first studied by this method. Observations upon the ballistocardiographic findings in patients with hypertensive and coronary artery heart disease are recorded; particular emphasis is placed upon a specific abnormality in the HIJK complex in the ballistocardiograms of many of these subjects.

Mandelbaum et al. (1951) conducted an observational in Hypertensive and coronary artery heart disease (n=100). Portable electromagnetic ballistocardiography vs. Normal subjects was evaluated on Abnormality in the HIJK complex on ballistocardiogram. The portable electromagnetic ballistocardiograph revealed specific abnormalities in the HIJK complex among patients with hypertensive and coronary artery heart disease compared to 100 normal subjects.
