Retrospective learning system for generating and retrieving patient records containing physiological data

A retrospective learning system is described for recording physiological conditions of a patient over a period of time and storing such data in a database in searchable format. The retrospective learning system includes a database to store a number of searchable records, each searchable record including data representing a physiological condition of a patient over a period of time. The system further includes a module to retrieve the records from the database based on a search query and to replay selected ones of the retrieve records. In one embodiment, at least a portion of the data included in the patient record is in a waveform format suitable for providing a waveform image. The patient record further includes data corresponding to the waveform data converted into a searchable format.
