Key result
Rule-based BSPM ECG mapping accurately localizes myocardial infarction across a 17-segment LV model.
Why the study?
A method to determine the location and extent of myocardial infarction using Body Surface Potential Map data was needed.
Does a rule-based method using extracted ECG features accurately determine the location and extent of myocardial infarction?
Does a rule-based method using extracted ECG features accurately determine the location and extent of myocardial infarction?
A simple rule-based method using extracted ECG features from Body Surface Potential Map data can accurately localize and determine the extent of myocardial infarction.
May support BSPM ECG for MI localization research; leaves open prospective validation before clinical use.
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.
