Abstract
Most methods which have been applied to the inverse problem in electrocardiography operate in the time domain of the data and use regularization techniques which minimize a measure based on total squared error. These methods have important weaknesses for clinical applications. Recent results have shown that frequency-domain parameters can be used successfully in detection, localization, and quantification schemes for the important case of myocardial ischemia. It is therefore worthwhile to investigate frequency-domain reconstructions techniques which have the potential to avoid these weaknesses. The authors explain one such technique, based on the minimum-relative-entropy reconstruction principle and discuss its application to this problem.Keywords
