An electrocardiographic baseline reconstruction method for rapid ventricular tachycardia

The authors describe a novel method for electrocardiographic (ECG) baseline reconstruction of rapid Ventricular Tachycardia (VT) by removal of the overlapping T-wave from electrocardiographic signal. Reconstruction is done sequentially by extracting information lying in RR-variation zone. This sequential algorithm yields a non-overlapping pure QRST-signal, which can be used to subtract overlapping T-waves from ventricular tachycardia. Finally the authors demonstrate the use of the method in Body Surface Potential Mappings (BSPM)
