All ECG 39

  1. Normal sinus rhythm
  2. T wave abnormality consistent with intracranial process or ischemia (Wellen's phenomenon)
  3. Prolonged QT interval

During an acute intracranial process such as intracranial hemorrhage or after carotid endarterectomy, dramatic ECG changes can be seen in the absence of any cardiac pathology. These include deep inversion of the T waves and prolongation of the QT interval. The connection between the brain and heart is poorly understood. These ECG changes can be confused with those of the Wellen's phonomenon which can have similar T wave changes and indicated myocardial ischemia, however the QT interval is usually normal in this setting.
