ABSTRACT

Oesophageal electrocardiography provides for an analysis of heart rhythm that must be considered more accurate than the one obtained in a conventional electrocardiogram. Bipolar intraoesophageal and oesophagosternal or oesophagoparasternal leads, using adequate electrode cables, permit recordings, satisfactory from a technical point of view, even when applying the methods of provocations (ergometry).
