Avoid the Phrase Electrocardi~ grqMmic “Changes”

Knowing Spodick to be fastidious in his use of terminology, I was surprised to read the first sentenceof the article “Electrocardiographic Features of Restrictive Pulmonary Disease, and Comparison with Those of Obstructive Pulmonary Disease,” in The American Journal of Cardiology, August 1, 1992, of which he is part author. He used the term “electrocardiographic changes. ” I think Spodick might agree that what he in fact intended to say was “electrocardiographic ab500

normalities” or “electrocardiographic pattern” or “ECG features” as in the title. More than just a semanticquibble, I am frequently called by emergency room physicians who claim to see “changes” in an ECG when indeed what they are describing is an abnormality with no prior ECG documentation to justify the term “change.” It is of courseunderstood that what has been meant by the term “change” has generally been “change from normal” (not good English in any case), but this could equally apply to “changes within normal,’ ’ which of course has yet another meaning. I hope Spodick would join me in a plea that the term “electrocardiographic changes” be confined to those in which a true “change” is documented, by deli&ion requiring at least 2 sequentialtracings. If what is meant is “abnormality,” then that term (or perhaps a shorter term of the same meaning) could be employed. If the word “change” refers to “change within normal,” as often appearsto be the casein this article, the term “pattern” or “features” would seema clearer description. Philip J. Millman, MD Watertown, New York 17 August 1992

REPLY: hIillman is, of course, absolutely correct and I wholeheartedly join him in his proposal that the word “change” be used in its precise (therefore appropriate) sense. “Abnormality” is basic, and if there is an abnormality, whether it is a “change” should remain in the realm of comparisonwith a previous status.As Millman notes, that status could be normal or abnormal. I am grateful to him for pointing this out. David H. SpOdlCk, MD, MC Worcester, Massachusetts 3 September 1992

MentalstrassandthaLeft Mcular Ejection Fraction

Ironson et al’ report that patients with coronary artery disease demonstrated greater reduction in ejection fraction during angerrecall than during other mental stress, such as giving a speech defending themselves against a hypothetical charge of shoplifting. In contrast, Rozanski

et al reported that a personally relevant, emotionally arousing speaking task clearly induced more ischemic abnormalities than other mental stress.*These tindings and the correlation of a compromised selfimage to coronary risk (coronary artery disease) suggest determining the emotional significance of speech by monitoring the frequency and duration of hesitation pausesof 1 second or more (4.79 f 2.48/rnim 1.50 f 0.33 second [mean & SD]), which correlate with coronary arterv diseaseand mood, respec&ely.3Ernest H.

Readership

Response

Our recent editorial that appeared in your journal, “Questions Unresolved by the Third International Study of Infarct Survival,” by Sobel and Collen has evoked a prodigious number of requests for reprints. In addition, I have received somecomplimentary comments about the importance of the airing of the views expressed.My purpose in writing to you is simply that as an editor you are undoubtedly subjected to distressing correspondence all too often. It seemsto be that you should be advised when the extensive readership of your journal and the journal’s remarkably positive and profound influence result in such an obvious and unusual response to a single article. I knew that The American Journal of Cardiology had profound impact, but I was surprised and delighted to seethat it is such a powerful vehicle for dissemination of clinically relevant information and views. Thanks for the opportunity you provided to us. Best regards. Burt011 E. &bel, MD St.Louis, Missouri 24 August 1992
