Abstract.
The analysis of a biomedical signal is a complex task due to inherent variations in time and
frequency, as well as individual physiology or pathology of patients. Added to this, doctors often are
not specialists with the ability to interpret the data in certain types of signals such as the
phonocardiogram, especially in marginalized regions. In response to such problems, we intend to
support medical diagnosis with a computational tool to analyze, manipulate and compare biomedical
signals. We interviewed doctors to determine system requirements, designed the interface and finally
implemented the software using the programming language C#. From automated data analysis and
screen resolution, the system calculates the scaling factors necessary to correctly display the signal.
Simultaneous display of two or more signals, horizontal zoom, scrolling, mark positioning and resizing
of the scales were added to meet the physician-defined requirements. The data and user inputs were
divided into three classes according to function: the Biosignal class for reading, storage and
manipulation of the raw data in the biomedical signal; the Format class for the resizing and
normalization information; and the Viewer class for the display and manipulation of the on-screen
signal.
