Bundle Branch Block Classification Based on Two Leads ECG using Random Forest

Arrhythmia is a heart disease that causes the heart to beat abnormally. One of the most common types of arrhythmia is Bundle Branch Block (BBB). Two types of bundle branch block commonly encountered are left bundle branch block (LBBB) and right bundle branch block (RBBB). Electrocardiogram (ECG) is a tool commonly used to detect arrhythmias. Bundle branch block is easier to detect using ECG leads V1 and V6. However, many studies use other leads, such as MLII, or do not specifically use leads V1 or V6 as references. Therefore, in this study, various leads of ECG will be used as a comparison to see which leads can classify LBBB and RBBB better. In addition, random forest is used to classify bundle branch block automatically. The classification results show that the lead that gives the best results is the combined lead MLII and V1, where the accuracy is 98.69%, precision is 98.44%, recall is 98.72%, and f1-score is 98.56%.
