title: Electrocardiographic abnormalities in neurological diseases.
abstract: OBJECTIVE
  To evaluate electrocardiographic abnormalities in patients with neurologic diseases.
  
  
  METHODS
  We studied 161 patients with neurologic disorders by analyzing the 12-lead electrocardiogram during the pathological process. An expert who did not know anything about the patients evaluated the traces.
  
  
  RESULTS
  Neurological process included brain tumor (41%), stroke (27.3%), cerebral aneurysm (15.5%), subarachnoid hemorrhage (6.8%), subdural hemorrhage (5%), and head injury (4.4%). Electrocardiograms were normal in 61% of cases, and the most frequent abnormality was ventricular repolarization (23.7%). The presence of T waves (4.6%) and prolonged QT intervals (8.8%) was the most characteristic of brain injuries.
  
  
  CONCLUSIONS
  We observed a lower incidence of electrocardiographic abnormalities than that described in the literature.
