Electrocardiographic changes after cervical laminectomy.
Striking T-wave inversions were observed in the postoperative electrocardiograms of a 64-year-old woman following an extensive cervical laminectomy. Except for the presence of a trace amount of CK-MB in a single serum specimen all her enzyme and isoenzyme studies were negative, and her clinical course was not suggestive of myocardial ischemia. Coronary angiography, including an ergonovine study, done 6 mth following the laminectomy were normal. Because of the nature of this patient's neurogenic origin of these T-wave changes is suspected.
