[Complex assessment of the electrophysiological changes in patients with right-ventricular cardiac loading].
In 216 patients with right ventricular cardiac overload the changes of 76 electrophysiological indices were studied--indices of the corrected orthogonal electrocardiogram after Frank, corrected orthogonal vectorcardiogram, spatial electrocardiogram and high-speed spatial electrocardiogram. The patients with right ventricular cardiac overload are divided into two basic groups--patients with systolic and patients with diastolic overload. The indices are assessed on the basic criteria of sensitivity, specificity and realization. Variation analysis as well as statistical comparison with 119 healthy persons are performed. On the basis of the results of the study "sets" of 4 indices each with 97-98% sensitivity are determined, indices from all methods used are included in the "sets". The conclusion is reached of the good possibilities of the electrophysiological methods when a combination of indices with the help of a computer is made.
