1. A system for automated recognition of hemodynamic parameters and waveform attributes comprising: an impedance cardiography device including at least one sensor configured to be externally placed on a patient and adapted to noninvasively provide at least one impedance waveform signal; a knowledge base including known data corresponding to various disease states; a processing device in operable communication with said at least one sensor and said knowledge base, said processing device configured to receive said at least one impedance waveform signal and calculate a hemodynamic parameter of the patient therefrom, identify waveform attributes on said waveform signal, measure said waveform attributes, measure said hemodynamic parameter, and cross-reference said waveform attributes and said hemodynamic parameter with said knowledge base data, and output a suggested likelihood of a particular disease state based on said cross-reference.
