Evaluation of Vectorcardiography Parameters Matrixed Synthesized

The form of analysis of the cardiac signal most used today is the electrocardiogram (ECG). However, in addition to this form of data visualization, there is the vectorcardiogram (VCG), that allows a visualization of the signal in 3 dimensions. This study aims to compare the different ECG to VCG transformation matrices Kors and Inverse Dower (iDower), by analyzing some known parameters taken from VCG’s mathematically synthesized from 12-lead ECG’s of amyloidosis patients. The idea is also to compare that similarity for patients with different types of amyloidosis. The study was done through the analysis of electrocardiograms taken from a sample of 12 humans who have amyloidosis, either mutant or wild-type. The results indicated that there is not much similarity between the signals, although the similarity was higher for patients with mutant amyloidosis than for those with wild-type amyloidosis.
