目的：观察脑出血是否能引起心电图（ＥＣＧ）异常。方法：５６只Ｗｉｓｔａｒ大鼠随机分为３组：对照组１０只，左侧内囊血肿组２２只，右侧内囊血肿组２４只。麻醉后，用监护仪监测动物的ＥＣＧ，将１２０μｌ新鲜鼠血注入大鼠内囊处，观察其ＥＣＧ变化。结果：右侧内囊血肿组的ＥＣＧ异常发生率为６２．５％（１５／２４），左侧内囊血肿组为３６．４％（８／２２），２组无统计学差异（χ２＝３．００５７，Ｐ＞０．０５）。ＥＣＧ异常表现为ＳＴ段上抬（２４／４６）、心房扑动（１２／４６）和频发室性早搏（７／４６）。７０．８％鼠（１７／２４）的ＥＣＧ异常发生在内囊血肿形成后３小时内。对照组在监测过程中未发现ＥＣＧ异常。结论：内囊血肿可引起ＥＣＧ异常。
Objective: To observe whether cerebral hemorrhage can cause electrocardiogram (ECG) abnormalities. Methods: Fifty-six Wistar rats were randomly divided into three groups: control group (n = 10), left inner capsule hematoma group (n = 22) and right right inner capsule hematoma group (n = 24). After anesthesia, monitor the ECG of the animal and inject 120 μl of fresh rat blood into the internal capsule of the rat to observe the ECG changes. Results: The incidence of ECG abnormalities in the right internal cyst hematoma group was 62.5% (15/24), in the left cyst hematoma group was 36.4% (8/22), there was no significant difference between the two groups (χ2 = 3.0057, P> 0.05). ECG abnormalities were ST-segment elevation (24/46), atrial flutter (12/46) and frequent premature ventricular contractions (7/46). An abnormality of the ECG in 70.8% of the rats (17/24) occurred within 3 hours after the formation of the internal capsule hematoma. The control group did not detect ECG abnormalities during the monitoring. Conclusion: Internal capsule hematoma can cause ECG abnormalities.
