AN INVESTIGATION OF THE APPLICATION OF SPATIAL VECTORELECTROCARDIOGRAPHY TO PROBLEMS OF CENTRAL CARDIOVASCULAR SYSTEM CONSTRAINT.
Abstract
The purpose of this study was to investigate methods to determine heart position under conditions of vibration by using vectorelectrocardiographic techniques. An experiment to validate a theory is described, based on conductivity inhomogeneities of tissues surrounding the heart and proposing amplitude modulation of electrocardiographic waveform frequency components under conditions of sinusoidal vibration. Results are presented which show that frequency analysis of the waveform does not yield the desired displacement information due to lack of physiological standardization. A proposed method of extending Ernest Frank's mirror image cancellation method to vibration problems by using time sampling and computer data reduction is presented. (Author)
