[Value of the esophageal ECG]

The Authors examined 20 patients suffering from anginose symdrome, whose standard ECG did not show remarkable alterations. In the same patients, oesophagus ECG did show clear signs of sub-epicardium lesion as well as necrosis, which interested the upper part of left ventricle's posterior wall; such zone is not explorable by traditional ECG. Hemodynamic poligraphic examinations were made as well, and thus also a reduction of cardiac inotropism was found out.
