22 patients presenting an "angina with normal coronarography" and 5 control subjects were subjected to a manometric exploration of the oesophagus in the basal state and under methylergometrine maleate (MEM) treatment. The MEM test is shown to be a good one for the induction of painful oesophageal dyskinesias, particularly in patients who had suffered in an inexplicable manner when that substance was administered for coronarography.
