Using high-resolution electrocardiography (HRE), we have previously examined the morphological aspects of the atriogram in a set of DZ triplets comparing the MZ and the DZ pairs [3]. We now repeated the recordings on the triplets, three years after the first studies, in order to evaluate the individual morphological reproducibility of the atriogram and the cardiovascular response to effort and to stress by means of provocative tests [1-3].

We studied a set of female DZ triplets aged 15 years, born normally at the 39th week of gestation, with two chorions and three amnions. We compared the responses to the individual provocative tests, and repeated the analysis of the atriograms after three years. We therefore used the HRE, the Bruce protocol ergometric test, and the sympathetic stimulation tests: handgrip test, cold pressure test, arithmetic mental test (Table).
