[False diagnosis of myocardial infarction due to inversion of the electrocardiographic leads in the right limbs (author's transl)].

An abnormal ECG suggested the diagnosis of myocardial infarction in a 65-year-old man who had suffered a transient chest pain. When the patient was admitted to the Hospital a new ECG and biochemical enzymes were normal, but and identical pathologic ECG was registered following inversion of the electrocardiographic leads in the right superior and inferior extremities. A prospective study of 160 adult patients has demonstrated that inversion of the leads in the right limbs frequently causes the appearance of pathologic Q waves (37.14 percent) and ischemic T waves (51.22 percent), especially in lead I and aVL. Number of pathologic Q and T waves may vary when they are present in the basal register, but we never observed their disappearance in all the precordial lead series. A constant finding was the marked low voltage of P, QRS and T in lead II due to the "distance" of the electrocardiographic leads right leg-left leg. Technical recognition may be difficult because P waves and QRS complex are frequently negative or isoelectric in aVR.

[Klippel-Feil syndrome and associated malformations. Comments on an unusual case].

An unusual association of Klippel-Feil syndrome and other abnormalities (Sprengel's deformity, 1st cervical and 1st dorsal spina bifida, homovertebral bone, scoliosis, plagiocephaly, basilar impression, pterygium colli, nanism, hypogenitalism, etc.) together with neurological signs of amyotrophic lateral sclerosis, in a 36-yr-old woman is reported. The clinical and radiological pictures are examined and the exterior morphology is examined. The three types of Klippel-Feil syndrome are discussed, together with the particular alterations observed in the present case: Sprengel's deformity, spina bifida, craniostenosis, basilar impression, etc.
