Entropy, Assessed by Homeostatic Dysregulation on Electrocardiograms Predicts Fracture and Mortality

3 days 11 hours ago
Entropy, characterized by increased disorder throughout biological systems, can be quantified by homeostatic dysregulation (HD). One potential measure of HD is the dispersion of points from a normal value, approximated at the individual level by Mahalanobis distance (D(M)). We hypothesized that greater HD in electrocardiogram (ECG) would also reflect greater HD in the musculoskeletal system which, in turn, would be associated with age and manifest as an increased risk of fracture independently...
