[目的]了解急性脑干梗塞患者早期心电图(ECG)的变化情况。[方法]用MAC-1200型十二导联心电图机对101例急性脑干梗塞患者进行ECG观察。[结果]101例急性脑干梗塞患者中有79例患者在发病24h内有不同程度、不同类型的ECG改变。其中以ST-T的改变较为多见,其次为各种心律失常,偶尔可见房室传导阻滞和急性心肌梗塞。[结论]急性脑干梗塞早期常伴随有继发性各种ECG改变,其中以ST-T的改变较为多见。 [Objective] To understand the changes of early electrocardiogram (ECG) in patients with acute brain stem infarction. [Method] The MAC-1200 12-lead electrocardiogram was used to observe the ECG of 101 patients with acute brain stem infarction. [Results] Among 101 patients with acute cerebral infarction, 79 patients had different degrees and different types of ECG changes within 24 hours of onset. Which ST-T changes are more common, followed by a variety of arrhythmias, and occasionally visible atrioventricular block and acute myocardial infarction. [Conclusion] The early stages of acute cerebral infarction often accompanied by a variety of secondary ECG changes, of which ST-T changes are more common.
