Abstract
New methods of characterising ventricular operations by measuring propagation characterisics of the repolarisation wavefront (the T wave) are disclosed, the methods use new descriptions of T wave Morphology Dispersion (TMD), Total Cosin R_ to _T (TCRT) and T wave energy residium to quantify the wavefront characteristics, these descriptors measure the spatial variability of the T wave Morphology, the vector deviations between the depolarisation and repolarisation wavefronts and the energy of the non-dipolar components of the ECG vector respectively. TCRT also provides a responsive descriptor for measuring autonomic tone. As such, has applications for improved pacing and autonomic nervous system monitors.
