Abstract
Neurologic and eeg examinations were made in 32 patients before open heart surgery and in most of them after surgery; 27 had eeg records made during the surgical procedure. Results of these examinations revealed a high percentage of abnormal eeg''s and neurologic examinations before surgical treatment in patients with heart disease (34%). In most of the patients who showed electrical abnormality (73%), this was predominant in posterior temporal, parietal, and occipital regions. The surgical procedure in most cases only temporarily affected the eeg record and the clinical neurologic picture. In 2 control patients having anesthesia and uncomplicated intratho- racic operations without perfusion, postoperative eeg''s were temporarily more abnormal than their preoperative tracings. It is suggested that congenital alteration of cerebral blood supply secondary to heart disease produces disturbances which prevent the normal maturation of electrical rhythms. This is manifested in adults by eeg abnormalities that resemble those frequently seen in children. Future correlation of neurologic and eeg findings with pathologic studies of the central nervous system will probably greatly contribute to the study of origin and development of cerebral electrical activity.Keywords
