title: [Use of esophageal leads in the diagnosis of myocardial infarct with a postero-inferior site].
abstract: The electrocardiographic diagnosis results from the verification of a anomalous waves in one or more derivations. There are, however, some cases of infarct in which the electrocardiogram appears regular and there are other different situations in which a more less profound "a" wave can appear in the D3 and aVF derivations. The Authors have considered four groups of patients, in which only the oesophageal ecgraphic has allowed to obtain the right diagnosis, succeeding in filling the gaps of the diagnostic possibilities of the standard ecgraphic.
