Abstract:
Estimated heart rate variability (HRV) may be used to determine a heart rate variability index. Based on a relationship between one or more variables and the HRV, a multiple regression analysis may be performed to reduce a confounding effect of the one or more variables on a relationship between the heart rate variability index and the one or more variables. This index may then be normalized from 0-100. A computer, or other suitable device, operatively connected to a field monitor capable of taking an EKG, may determine an HRV index, which can then be used to determine the likelihood of a variety of medical conditions. These conditions can include such things as the likelihood of an abnormality were a computed axial tomography scan to be performed, thus, in some cases, reducing or eliminating the need for performing such a scan.
