[Stereovectorcardiography. Analysis of congenital excitation-conduction anomalies using a new type of microelectronic equipment (author's transl)].
The results of the first clinical trial of a stereo-VCG used for the quantitative and qualitative analysis of congenital anomalies of excitation-conduction are elaborated and discussed. Normal values for paediatric cardiological patients were calculated for the following parameters with the help of measurements from 78 patients: Pmax, Rmax, Tmax-stereovectors, their elevation and azimut, the stereo-angle between Rmax/Tmax, Pmax/Tmax and Pmax/Rmax as well as the periods from the beginning of the ventricular excitation until Rmax and Tmax. The patients were divided into 4 age groups. The group of normal individuals was compared with 22 patients having anomalies of conduction. The results show that this new technique allows more differentiated analyses of the vector loops registered according to Frank's orthogonal corrected registering system than the conventional measurements in cases of congenital anomalies.
