Congenital heart block may be initiated or present as a first degree heart block [4]. In the present study, all Swedishpatients (n = 64) were systematically followed by serial Doppler echocardiographic recordings during pregnancy to detect signs of both first, second and third degree heartblock. This made it possible to identify foetuses with signs of AVB I in the group of foetuses with NHR. By using anova itwas demonstrated that the degree of foetal cardiac involve- ment was a highly significant factor of variance for the maternal p200 antibody levels (P < 0·005). Mothers of both foetuses with AVB II-III and those with signs of AVB I hadhigher p200 levels than those with a foetus without cardiac involvement (Fig. 4).

Using the assay for analysis ofthe combined serological material from Finland, Sweden andthe USA, there was a significant difference in p200 antibody Sensitivity= 90.5 levels between mothers of children affected and not affected by AVB II-III, but also an overlap in p200 levels between the two groups of mothers. The material was therefore stratified to identify potential groups of patients where p200 antibod-ies could be of practical clinical value. Further, we limitedanalysis of p200 levels to Ro52-positive sera, as the main objective of the study was to relate the value of p200 anti- body analysis to Ro52 antibody analysis. In stratification, adifference in p200 levels between the three national cohorts became evident, where Finnish and American sera had gen-erally lower p200 antibody levels than Swedish sera, and alsowhen only Ro52-positive sera were included in analysis. In Swedish and American Ro52-positive sera, the p200 anti- body levels were significantly higher in mothers of infantswith AVB II-III than in mothers of infants with normal heart rate.
