Abstract: A method for extracting segments from an electrocardiogram tracing is disclosed. The method selects an electrocardiogram tracing for segment extraction, and associates a dosing time or other time point with the electrocardiogram tracing to align an extraction template within the electrocardiogram tracing for segment extraction. The electrocardiogram tracing is scanned for artifacts and the electrocardiogram tracing is annotated if any artifacts are discovered. If there are any artifacts present in the segment designated for extraction by the extraction template, the extraction template is modified to avoid the artifacts. If the extraction template cannot be modified, the electrocardiogram tracing is annotated as unextractable. If artifacts are not present in the segment designated for extraction by the extraction template or the extraction template was successfully modified, the designated segment is extracted from the electrocardiogram tracing and written to a storage medium.

Abstract: A method for analyzing a subject-visit group of ECG waveforms captured digitally on an electrocardiograph machine, on a Holter monitor device or digitized from paper electrocardiograms. A cardiologist selects a subject-visit group from a number of subject-visit groups, and each ECG waveform of the subject-visit group is scanned for artifact. Those ECG waveforms containing artifact are annotated appropriately. A determination is made if measurement calipers are present in each ECG waveform, measurement calipers are added to ECG waveforms lacking measurement calipers, and a preliminary interpretation is assigned to each ECG waveform that lacks a preliminary interpretation. Each ECG waveform is assigned a grouping metric, and the ECG waveforms are segregated according to their grouping metric for display and evaluation.

Abstract: A method for transfer of electrocardiograph data between a remote processor connected to a central processor via a network. Identification information concerning a test subject associated with electrocardiograph data stored on a portable storage medium is entered into a remote processor. The remote processor extracts the electrocardiograph data from the portable storage medium and transmits the identification information and the electrocardiograph data from the remote processor to a central processor. Upon receipt and storage of the electrocardiograph data, the central processor transmits a release message to the remote processor to enable erasure of the electrocardiograph data from the portable storage medium.
