RESUMO
The meaning of normalization of abnormal T waves during exercise is still unclear, twenty patients with this electrocardiographic pattern during treadmill stress test were studied with coronary arteriography. They were classified in two groups: Group I: In which 3 patients had isolated "pseudonormalization" of the T wave, and Group II with "pseudonormalization" of the T wave plus a positive stress test or an old myocardial infarction. Results allowed us to conclude that this phenomenon per se is not a diagnostic clue of coronary injury; however when we observe it associated with a positive stress test or an old myocardial infarction it may be indicative of severe and multiple coronary vessel injury.

Se informa un caso de tetanos generalizado grave, tratado con dantroleno. Inicialmente el enfermo se manejo en la forma convencional con diazepan y cloropromazina, presentando depresion en el estado de conciencia y de la funcion respiratoria. El uso del dantroleno (100 mg/dia), produjo una excelente respuesta miorrelajante, con minima depresion respiratoria. Se corroboro la accion terapeutica al reaparecer el cuadro espastico 12 horas despues de suspender el dantroleno, y desaparecer al reiniciarlo
