title: [An ECG-anatomical comparison in a case of Williams' syndrome].
abstract: A case of Williams' syndrome in a 22 years old man, is described. Clinical data, as well as those of laboratory and of imageneology study, are reported. An electro-anatomical comparison permitted to verify the value of electrocardiographic signs of enlargement of the four heart chambers, due to a mixed overload. It permitted also to establish the value of the signs of the interatrial block, probably due to myocardial atrial fibrosis, and those suggesting hyperkalemia. The electrocardiogram always is very useful because it furnishes certain functional aspects permitting to allow structural inferences, in following subjects with congenital or acquired heart diseases.
