T-wave alternans influence on vectocardiographic parameters

The influence of T-wave alternans (TWA) on vectocardiographic parameters has been presented. Alternations in the length and the angle of T-wave loop vector have been found between odd and even beats in electrocardiograms with detectable T-wave alternans. The study shows the significance of changes of T-wave loop vector length and angle in the process of shaping Twave alternans signal. The aim of the study was to improve TWA detection process. The results showed the advantages of using vectocardiographic analysis for Twave alternans detection.
