A new approach to estimate ECG signal source using voltage divider technology

In this study a new method for electrocardiogram (ECG) signal source estimation using voltage divider technology has been developed. This method enables simultaneous acquisition of two kinds of information from one single electrode, i.e., the signal´s source potential and its position. Conventional methods require many electrodes to estimate the signal source accurately, and this imposes extra burden on the subjects. Our new signal source estimation method would improve the accuracy of the signal source estimation and reduce the number of surface electrodes. In this study, we evaluated our estimation method in a human ECG measurement model. Results demonstrated that the signal source position could be estimated well in this model.
