SYSTEM AND METHODS FOR DISPLAYING MEDICAL DATA

摘要

Systems and methods for displaying medical or physiologic data are disclosed. The system can receive medical data such as a physiologic trend indicative of worsening of heart failure. The system can generate a graphical representation of the medical data in a two-dimensional or a higher-dimensional coordinate space. The graphical representation can include line segments indicating temporal variation of the medical data. The system can determine a desired range, including lower and upper bounds, for displaying the medical data using signal statistics and a correction factor, and specified number of tickmarks between the desired LB and LB. The desired lower and upper bounds can enhance visual perception of temporal variation of the medical data, and thus to facilitate data interpretation and clinical decision making. A display unit can display the graphical representation of the medical data within the desired lower and upper bounds.

主权项

1. A system for displaying medical or physiologic data, comprising:
an input circuit, configured to receive medical or physiologic data; a processor circuit, configured to:
generate a graphical representation of the medical or physiologic data in a two-dimensional or a higher-dimensional coordinate space, the graphical representation including line segments indicating temporal variation of the medical or physiologic data; anddetermine a desired range of at least one axis for displaying the medical or physiologic data, including determining a desired lower bound (LB) and a desired upper bound (UB) using an initial signal statistical parameter and a correction factor (δ), wherein the correction factor δ is computed using at least one of a signal range of the received medical or physiologic data, a specified number of tickmarks for the at least one axis, or a noise level of the received medical or physiologic data; and a display unit, coupled to the processor unit, configured to display in the coordinate space the graphical representation of the medical or physiologic data within the desired range.
