Patent ID: 7367951

Claim:
A cardiovascular analysis system comprising: an implantable medical device having a sensor adapted to sense a hemodynamic pressure in a heart over time, wherein the implantable medical device generates hemodynamic pressure waveform data based upon the sensed hemodynamic pressure; and a processor for analyzing the hemodynamic pressure waveform data to provide an indication of cardiovascular and cardiopulmonary health based upon prominent peaks in the hemodynamic pressure waveform data wherein the processor indicates an adverse health condition that correlates to identification of a prominent primary peak and a prominent secondary peak of the hemodynamic pressure waveform data, and wherein the prominent secondary peak corresponds to a systolic pressure of a cardiovascular pulse cycle, wherein the processor identifies a prominent secondary peak of the hemodynamic waveform data when a peak pressure value of the hemodynamic pressure waveform data occurs after about 210 milliseconds of hemodynamic pressure sensing and a first derivative of the hemodynamic pressure waveform data includes a value greater than about 128 mmHg/sec between a period of hemodynamic pressure sensing occurring between about 188 and about 312 milliseconds of sensing.
