Claim Text:
1. An active medical device comprising: at least one sensor configured to receive a heart rate signal and an endocardial acceleration signal from a patient; a microcontroller configured to receive the heart rate signal and the endocardial acceleration signal, and to calculate a hemodynamic parameter determined from the endocardial acceleration signal representative of myocardium contractility; wherein the microcontroller acquires a pair of values for each of a plurality of successive cardiac cycles, wherein: wherein the microcontroller is configured to distribute the pairs of values from the plurality of successive cardiac cycles into discrete bins corresponding to discrete ranges of two or more heart rate values to develop a profile for analysis, wherein the profile comprises a plot, for each of the discrete bins, of a representative hemodynamic parameter calculated from the hemodynamic parameter of each of the pairs of values distributed in the discrete bin; wherein the microcontroller is configured to conduct an analysis of the profile comprising calculating an index representative of the patient's clinical status; and a transmitter for transmitting data comprising the index representative of the patient's clinical status from the device to a remote system.
