However, there are both technical and theoretical problems with QT measurements. We propose two robust methods for the quantification of the ventricular repolarization abnormalities: i) The quantification of the inter-lead morphology differences of the T wave (T Wave Morphology Dispersion - TMD) ii) The analysis of the T wave wavefront direction with respect to the QRS complex (Total Cosine R_To_T - TCRT). Sensitivity and specificity of 82% (84%) in supine position and 77% (79%) in standing position were achieved for TMD (TCRT). Both parameters were more reproducible than conventional QT interval based parameters.EnglishSensitivity analysisWaveform analysisT-wave morphologyElectrocardiographyConference Paper10.1109/CIC.1999.825905
