Zjištění vlivu Hisovské stimulace na VCG průběhy

Abstract

This diploma thesis deals with the influence of His bundle pacing on VCG waveforms. The work includes a theoretical part to get acquainted with His bundle pacing and vector cardiography. VCG signals are obtained by the least squares transformation method from a 12-lead ECG. To compare the achieved type of stimulation, the GUIfig.m software was created in the MATLAB programming environment, which assesses QRS complexes based on VKG. The software should assist in determining what type of stimulation is being achieved at the pacing lead anchor site. The software assesses the stimulated QRS complex with the native one according to the correlation coefficient, MSE and Cosine similarity. An integral part is a graphical comparison of the signals of individual axes and the resulting VCG curve in three planes. The results of the patients are finally compared and evaluated. Further development of this work could be realized as a doctoral thesis.
