Patent ID: 7925337

Claim:
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: a first linear axis representing ST-segment deviation values; and a second linear axis representing the plurality of leads, wherein each of the plurality of leads is associated with a respective location along the second linear axis; displaying a first set of graphic indicia representing the baseline ST-segment deviations, wherein each graphic indicia in the first set 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 graphic indicia representing the current ST-segment deviations, wherein each graphic indicia in the second set 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 displaying the first set of graphic indicia and the second set of graphic indicia comprises: for the first set of graphic indicia, displaying a first bar graph at each of the locations along the second linear axis corresponding to a respective lead, wherein each first bar graph graphically represents the baseline ST-segment deviation for the respective lead; and for the second set of graphic indicia, displaying a second bar graph at each of the locations along the second linear axis corresponding to a respective lead, wherein each first bar graph graphically represents the current ST-segment deviation for the respective lead; wherein displaying each first bar graph comprises: displaying the first bar graph between a first value relative to the first linear axis and a second value relative to the first linear axis, wherein the first value corresponds to the isoelectric value, and wherein the second value corresponds to the baseline ST-segment deviation for the respective lead; wherein displaying each second bar graph comprises: displaying the second bar graph between the second value relative to the first linear axis and a third value relative to the first linear axis, wherein the third value corresponds to the current ST-segment deviation for the respective lead; and sloping at least a portion of the second bar graph to or from the third value to indicate a trend in the ST-segment deviation over time for the respective lead.
