Giant negative T waves after maxillofacial surgery.
A patient developed strongly negative T waves following anesthesia for maxillofacial surgery. The electrocardiogram was normal preoperatively, except for a single premature ventricular depolarization, and no abnormalities were noted during the operation. Postoperatively, the T wave gradually inverted in almost all leads and approached the criterion of -10 mm for giant negative T waves in V3 2 days postoperatively. The T wave returned to normal approximately 4 months later. Although the T-wave inversion in this patient may have been caused by surgical trauma to the sympathetic nerve supply to the heart or by myocardial infarction, the exact cause remains undetermined.
