Graphic visualization of ECG estimated myocardial infarct size using the standardized seventeen segment bull´s eye plot

The bull´s eye plot has been successfully introduced in multiple cardiac imaging diagnostic modalities and standardized by AHA in recent years. The ECG estimated myocardial infarct (MI) size is a quantitative measure of the size of the infarct region in left ventricular myocardium and is a proven tool to assist cardiologists in clinical decision making. MI size has been presented as a percentage of the left ventricle (LV) mass based on Selvester ECG scoring system. The scoring system has 50 ECG criteria with corresponding points. The reported MI size is not associated with a specific location in LV. This study applied the Selvester scoring system and bull´s eye plot to create a quantitative MI size presentation with visual location in the LV. The automated Selvester scoring algorithm was validated using a database of 688 ECGs with and without MI. The automated ECG-MI size was tested against two cardiologists´ manual scores resulting in 94% correlation.
