ABSTRACT
In this study, a method for determining the location and extent of myocardial infarction using Body Surface Potential Map data of PhysioNet challenge 2007 database is presented. This data is related to four patients with myocardial infarction. We used two patients as training set to determine rules and two other patients as testing set of the proposed model. First, T-wave amplitude, T-wave integral, Q-wave amplitude and R-wave amplitude as four features of ECG signals were extracted. Then we defined several rules and proper thresholds for localization and determining the extent of myocardial infarction. To determine the precise location and extent of myocardial infarction, 17-segment standard model of left ventricle was used. Finally, overall accuracy of this method was shown with SO, CED and EPD parameters. We obtained 1.16, 1 and 5.3952 for SO, CED and EPD, respectively, in our test data. Two main advantages of this method are simplicity and high accuracy.

Figure 8: Relationship between vertical and horizontal lines on the torso plane and all parts of the standard model of left ventricle

Mentions: As shown in Figure 8, six orange circles (horizontal lines 1-6) with the electrodes in torso plane correspond to basal; the next six lines shown in purple, i.e. horizontal lines 7-12 on the torso plane, correspond to mid-cavity; and five blue horizontal lines 13-17 correspond to apical region. In fact, this figure shows the relationship between horizontal and vertical lines in the torso plane with standard model segmentation of LV.
