Abstract
目的 探讨ST-T改变与脑卒中的相关性、发生机制及临床意义.方法回顾分析脑卒中患者2 160例心电图资料;比较ST-T明显改变者80例(观察组)和ST-T无明显改变者98例(对照组)的临床资料,包括合并其他常见病、出现心电图异常的情况.结果 2 160例中出现心电图异常1 327例,其中ST-T改变756例,占异常心电图的56.97%.与对照组比较,观察组合并高血压、冠心病、呼吸衰竭、电解质紊乱、心脏扩大及多种心电图异常发生率高(P＜0.05或P＜0.01).结论脑卒中患者心电图ST-T的改变,部分是受神经-体液及代谢-营养障碍的影响而出现的变化,即神经原性改变,可随病情好转而变化;部分则与原有的基础病相关,受其心脏在功能上或器质上已出现的病理性改变而影响,不随病情而变化。
