In Reply: Dr Wrenn is correct. Perhaps not surprisingly, we support his diagnosis of an innocent mistake. In the redrafting of our manuscript, the superscripts for references 52 and 53 were interchanged. As a result, the 1976 article by Dr Schwartz describing the common use of the GI cocktail to distinguish cardiac from esophageal chest pain was misattributed to Wrenn (publication precocity) and Wrenn's subsequent article challenging this practice to Dr Schwartz. We apologize for this typographical error and for necessitating the cocktail nostrum Wrenn describes, GI or otherwise.
