In the paper entitled "Intramural Depolarization Potentials in Myocardial Infarction: A Preliminary Report," by Prinzmetal, Kennamer, Shaw, Kimura, Lindgren and Goldman, published in the January 1953 issue of CIRCULATION, one statement requires correction. In the next to last sentence of the foreword, it is stated: "In the normal ventricle, positive depolarization potentials greatly predominate over negative potentials." This sentence should read: "In the normal ventricle, negative depolarization potentials greatly predominate over positive potentials."
