目的探讨急性肺栓塞(PE)患者药物治疗前后心电图改变及临床意义。方法回顾性分析23例PE患者治疗前后心电图的改变。结果急性肺栓塞经治疗后窦性心动过速、SⅠQⅢTⅢ、胸前导联T波倒置加深、aVR导联出现终末R波增高、顺钟向转位、电轴右偏、期前收缩等心电图指标较治疗前有明显改善,差异有显著意义(p<0.05)。结论心电图在急性肺栓塞诊断中虽然是非特异性的,但如能结合临床症状并及时仔细观察心电图改变,对急性肺栓塞的诊断有重要意义。
Objective To investigate the changes of electrocardiogram (ECG) in patients with acute pulmonary embolism (PE) before and after drug treatment and its clinical significance. Methods Retrospective analysis of 23 cases of PE patients before and after treatment of ECG changes. Results Acute pulmonary embolism after treatment of sinus tachycardia, S Ⅰ Q Ⅲ T Ⅲ, thoracic aortic T wave inversion deepening, aVR lead appears elevated terminal R wave, clockwise shift, right axis deviation, systolic and other ECG The index was significantly improved compared with before treatment, the difference was significant (p <0.05). Conclusions Although the electrocardiogram is non-specific in the diagnosis of acute pulmonary embolism, it is of great significance to diagnose acute pulmonary embolism if it can be combined with clinical symptoms and carefully observe the ECG changes in time.
