Abstract: A method of automatically selecting a physiological data manipulation process. After raw data including an asynchronous component having diagnostic information and including a synchronous component is received, the asynchronous component is separated from the synchronous component. A data manipulation process based on the diagnostic information is automatically selected based on the signal conditions generated during an analysis process.

Abstract: A method and apparatus for performing serial comparison between electrocardiograms (ECGs) acquired from a patient. The method includes acquiring ECGs from a patient with an acquisition device and using the acquisition device to perform a serial comparison between at least two of the acquired ECGs. The apparatus is an acquisition device including an acquisition module for acquiring ECGs from a patient and a signal processor for performing a serial comparison between at least two of the acquired ECGs.

Abstract: A method of displaying a representation of a physiological signal produced by a patient. The method includes the acts of obtaining a portion of at least one physiological signal acquired from the patient, determining an area to display, and constructing a virtual image representing at least a portion of the patient. The virtual image including (M) polygonal areas. The method further includes transforming the obtained signal to a plurality of values, assigning each value to one of the (M) polygonal areas, assigning a visual characteristic to each polygonal area based in part on the assigned values, and displaying at least a portion of the virtual image including the assigned visual characteristics. The invention further provides a method of optimal feature selection for the classification of the physiological signals produced by a patient.
