据报道,中风后心电图(ECG)出现异常的去极化改变,包括T波倒置,Q-T间期延长、ST段抬高或压低。这些改变在蛛网膜下腔出血(SAH)后尤为常见。研究显示半球病变比脑干损伤更易引起ECG变化。脑内岛叶手术刺激提示右侧岛叶介导交感性心血管反应中起主导作用。作者通过ECG、血压、心率探讨SAH的偏侧性及出血部位在介导心血管反应中的作用。

It has been reported that abnormal depolarization changes occur after electrocardiogram (ECG), including T wave inversion, prolongation of Q-T interval, elevation or depression of ST segment. These changes are particularly common after subarachnoid hemorrhage (SAH). Studies have shown that hemispheric lesions are more likely to cause ECG changes than brainstem lesions. Stimulation of intracerebral island islets suggests that right island mediates a predominantly sympathetic cardiovascular response. The author through the ECG, blood pressure, heart rate SAH laterality and bleeding site in the role of mediating cardiovascular responses.
