Abstract:
1. A method for monitoring a patient and graphically representing ST-segment deviations, the method comprising: acquiring electrocardiogram (ECG) signals from a plurality of leads, each ECG signal including a sequence of ST-segments between a QRS complex and a T wave; determining a baseline ST-segment deviation from an isoelectric value for each of the plurality of leads; determining a current ST-segment deviation from the isoelectric value for each of the plurality of leads; displaying a graph comprising: displaying a first set of bar graphs representing the baseline ST-segment deviations, wherein each first bar graph is displayed with respect to one of the locations corresponding to a respective lead and is aligned relative to the first linear axis based on the baseline ST-segment deviation for the respective lead; and displaying a second set of bar graphs representing the current ST-segment deviations, wherein each second bar graph is displayed with respect to one of the locations corresponding to a respective lead and is aligned relative to the first linear axis based on the current ST-segment deviation for the respective lead; wherein each second bar graph has a width in the direction of the second linear axis that is narrower than a width in the direction of the second linear axis of the corresponding first bar graph for a respective lead; wherein each second bar graph has an origin with respect to the first axis at the baseline ST-segment deviation for a respective lead and extends along the first axis in a positive or negative direction depending on whether the current ST-segment deviation is respectively greater or less than the baseline ST-segment deviation; and wherein, if the current ST-segment deviation is positive and is less than the baseline ST-segment deviation for a particular lead, the second bar graph for the particular lead extends in the negative direction into the corresponding first bar graph.
