ABSTRACT:
Systems and methods are provided for monitoring a patient and graphically representing ST-segment deviations. A receiver acquires, from a plurality of leads, electrocardiogram (ECG) signals that each includes an ST-segment. A processor processes the ECG signals to determine baseline and current ST-segment deviations relative to an isoelectric value. A display module displays a graph that includes a first axis representing ST-segment deviation values and a second axis representing the plurality of leads. At each location along the second axis representing a respective lead, the graph displays a first set of graphic indicia representing the baseline ST-segment deviations and a second set of graphic indicia representing the current ST-segment deviations. In certain embodiments, the graphic indicia are represented by bar graphs. In other embodiments, the graphic indicia are represented by symbols that may be connected by line segments.
