Accuracy of ECG Algorithms in localising within the LVOT vs RVOT
Algorithm A Algorithm B Algorithm C
Assessor 1 79% 67% 50%
Assessor 2 88% 67% 63%
Assessor 3 83% 71% 58%
Accuracy of ECG Algorithms in sub-localising within the RVOT: septum vs free-wall
Algorithm A Algorithm C
Assessor 1 42% 37%
Assessor 2 58% 53%
Assessor 3 37% 42%

ECG = electrocardiographic; LV = left ventricle; RV = right ventricle; RVOT = right ventricular outflow tract.
