Abstract :
The authors investigate the accuracy and stability of ECG inverse solutions by applying the Self Constraint Super Resolution (SCSR) Method. Using the technique relative error (RE) and correlation between true epicardial potentials and estimated ones are calculated at 0.62 and 0.86 respectively
