[The genetic influence on the labile pseudo-ischemic T-wave (author's transl)].

After the demonstrated familial incidence of the "labile pseudo-ischemic T-wave" patterns, a research has been carried on in order to ascertain the possible genetic conditioning of the anomaly. The analysis of the pattern of the families, formed starting from the subjects carrier of the above-mentioned pattern, carried on with the Haldane sibships method corrected with that proposed by Lejeune, leads to affirm that the models of hereditary transmission able of explaining the found out distributions are of a not simple recessive type. The distribution of frequence of the subjects by "aplotype HLA" does not permit to settle a reliable correlation between the considerated electrocardiographic anomaly and the aplotype, at least as far as the number of the examined cases is concerned.
