急性肺栓塞药物治疗前后的心电图观察

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。

ECG changes before and after the treatment of patients with acate pulmonary embolism

Objective To discuss electrocardiographic(ECG) changes in acute pulmonary embolism and its clinical significance. Methods ECG characteristics were analyzed before and after treatment in 23 patients with acute pulmnary embolism. Results The parameters such as sinus tachycardia, SⅠQⅢTⅢ or QⅢTⅢ, ring bundle branch, ECG showed T to deepen on of precordal leads, terminal R raised up of AVR lead,clock wise rotation, right axis deviation and premature beats improved significantly after treatment(p<0.05). Conclusion Combining with symptoms such as dyspnoea,chest pain and cough,non-specifit ECG changes are of important values in diagnosing acute pulmonary embolism patients.
