Abstract: An example system provides a multi-stage workflow processing and analysis platform. The system may access first data associated with a patient and provide, for display on a client device, a graphical user interface that displays workflow elements and data points of the first data. In some instances, the system may receive, via the graphical user interface, an input relating a workflow element with a data point associated with the patient, which workflow element may define an action. The system may execute the workflow including the action defined by the workflow element, receive second data based on the workflow, and provide a graphical interface displaying the first data and the second data on the client device.

Abstract: Methods and apparatus for utilizing multiple sources of physiologic data to enhance measurement robustness and accuracy. In one embodiment, phonocardiography or “heart sounds” data is used in combination with one or more other techniques (for example, impedance cardiography or ICG waveforms, and/or electrocardiography or ECG waveforms) to provide more accurate and robust physiological and/or hemodynamic assessment of living subjects. In one variant, the aforementioned methods and apparatus are used to improve ICG fiducial point (e.g., B, C and X point) detection and identification accuracy. Moreover, the new ICG fiducial points that may be clinically important may be identified using the disclosed methods and apparatus. In a further aspect, the invention discloses methods and apparatus for utilization of ICG and/or ECG waveform information to improve the identification and characterization of heart sounds (such as e.g., S1, S2, S3, or S4 heart 20 sounds), murmurs, and other such artifacts or phenomena.

Abstract: An improved method and apparatus for non-invasively assessing one or more physiologic parameters, such as for example those associated with the circulatory system of a living organism. In one exemplary embodiment, the invention evaluates cardiac events (e.g., beats) present within an ECG waveform to determine which beats should be retained and which rejected. This evaluation is conducted based on a hierarchical method, wherein the ECG noise and morphology, as well as various aspects of the Delta Z (change in thoracic impedance), are utilized to evaluate beats for retention/rejection. In one variant, fuzzy models are used in conducting the foregoing evaluations. Parameter median filtering is also optionally applied. The foregoing techniques increase the accuracy, stability and robustness of any systems (e.g., impedance cardiographic or otherwise) which make use of the events. Improved impedance cardiographic apparatus and methods of treatment are also disclosed.

Abstract: A method for integrating a picture archiving and communication system (“PACS”) and a voice dictating or speech recognition system (collectively “voice dictation system”) is provided. The method includes logging in to a PACS. The method also includes automatically logging in to a voice dictation system responsive to the logging in step and opening an image file in the PACS. The integration method further includes automatically creating a dictation file associated with the image file in the voice dictation system responsive to at least one of the logging in step, the automatic logging in step or the opening step. The method may optionally include sending a predetermined identifier to the dictation file to associate the image file with the dictation file. The method may additionally optionally include performing the automatic logging in step responsive to the PACS being in a dictation mode.
