selection and measurement of the mpi and thus the sympathetic and parasympathetic components of autonomic balance at rest and during dynamic isotonic exercise and recovery is described the invention will further define risk of death using a kaplan meier plot for certain translated variables the method will enable physicians to collect view track and manage complicated data from multiple sources using simple well understood visualization techniques to better understand the consequences of their therapeutic actions application_number US 89175204 A description the following detailed description with respect to patient data is intended to be exemplary of a preferred method of utilizing the concepts of the present invention and is not intended to be exhaustive or limiting in any manner with respect to similar methods and additional or other steps which might occur to those skilled in the art the following description further utilizes illustrative examples which are believed sufficient to convey an adequate understanding of the broader concepts of processing data from a plurality of classes of related variables to those skilled in the art and exhaustive examples are believed unnecessary as indicated above one class of data dynamic cardiopulmonary dcp is obtained using physical exercise testing performed in accordance with a standardized workload protocol as the forcing function to elicit physiologic changes resulting from increasing amounts of workload such data can be viewed as a description of the primary u201c endpoint u201d for a wide variety of medical therapies u2014 data describing how an individual is able to function in the physical world in terms of the physiologic changes that the individual experiences when engaged in the performance of physical work the physiologic changes are measured using a cardiopulmonary exercise testing.
