急性颅脑损伤患者心电图改变

本文报告了43例急性颅脑损伤患者心电图和血压、心率的变化。左室高电压、Q-T 间期延长、T 波及S-T 段异常是急性颅脑损伤后最常见的心电图改变。Q-T 间期延长似乎与颅脑损伤的程度和预后密切相关。如果患者能安全渡过急性期,则本组79.3%病例的异常心电图可消失。急性颅脑损伤后,高血压和心动过速的发生率在本组病例中均超过39%。据信,急性颅脑损伤后心电图和血流动力学的变化主要系交感神经递质释放增多所致。同时讨论了对急性颅脑损伤患者异常心电图和高血压的合理治疗。

Changes of electrocardiograms in patients with acute brain injuries

The changes of electrocardiograms,blood pressure and heart rate of 43 acute brain-injured patients were reviewed.It was found that hyperpotential of left ventricular,prolonged QT interval, elevated ST segments and T waves variation were the most freguent changes.Prologed QT intervals seemed to closely relate to brain injured degree.If the acute stage was safely passed through,79.3% of abnormal electrocardiograms of the patients could disappear.After brain injuries,hypertension and taehyeardia were more than 39% of the cases.It is believed that all above could be explained by increased sympathetic tone.The article also discussed the rational managements of abnormal electrocardiograms and hypertension in brain-injured patients.
