Selected transformation methods and their comparison for VCG leads deriving

Vectorcardiography (VCG) as an alternative form of 12-lead ECG is another method measuring the electrical activity heart. The use vectorcardiography in clinical practice not common, but VCG leads can be derived from ECG. has proven to a useful and more accurate tool for diagnosing various heart diseases within automated detection. This paper presents application four transformation methods namely: Kors regression, IDT, QLSV Quasi-Orthogonal obtain VCG. A total 20 physiological records with diagnosis myocardial infarction were used. For records, regression achieved best results X Y relative deviation < 1%, correlation percentage similarity > 99%. In lead Z, most 98% pathological all was 2.2%, 93% 97%. From these results, there possibility creating new existing ones order transformation.
