Analýza animálního EKG

Abstract

The diploma thesis deals primarily with the electrical axis of the heart and the methods of their calculations in the frontal plane. In the theoretical part are described the methods of data collection for calculating the electrical axis of the heart, i.e., electrocardiography and vectorcardiography. In the practical part were developed and compared three ways of detecting Q, R and S oscillations from which the angles of the electric axis of the heart are calculated. Four methods of transformation of ECG to VCG were used to calculate from transformed VCG leaks. Based on the scientific literature, relationships for calculating the angle of the electric axis of the heart from limb ECG leads, from orthogonal VCG leads and from transformed VCG lesions were established. The aim of the thesis is to compare the different methods of calculating the angles of the electrical axis of the heart in the ECG and VCG records in order to use the selected relationships in the ECG animal records.
