Abstract
Normal standards for ballistocardiogram amplitude have been estimated by statistical methods from a series of 194 healthy men and women. The application of new knowledge of the genesis of ballistocardiograms has resulted in normnal standards with a smaller scatter than those previously formulated, and so the ability to detect cardiac abnormality has been correspondingly increased.Keywords
