To investigate influences of head injury on the cardiovascular function, the electrocardiograms were examined in a total of 70 cases of head injury without pre-existing cardiovascular disorders.
In 60 of 70 cases, the electrocardiograms were examined either before or after the craniotomy, and in the remaining cases, both before and after the craniotomy.
The results were as follows:
1) The incidence of abnormal electrocardiogram in head injury was 45% of the cases.
Among the abnormal electrocardiograms, nonspecific T change and arrhythmia were the most frequent findings.
2) The electrocardiograms before the craniotomy showed higher incidence of abnormal electrocardiograms than that after the crantiotomy, and nonspecific T change was the most frequent abnormal finding before the craniotomy, while arrhythmia after the craniotomy.
3) The incidence of abnormal electrocardiograms was higher in cases with serious or deeply seated lesions of the brain, and in expired cases.
