急性肺血栓栓塞症44例心电图分析

摘要

Objective To study the characteristics of electrocardiogram (ECG) of acute pulmonary thrombo-embolism. Methods ECGs recorded at admission and two to four weeks after thrombolytic or anticoagulant thera-pies in 44 patients with acute pulmonary thromboembolism were analyzed retrospectively. Results ECG changes were found in 42 cases (95.5%) at admission, sinus tachycardia in 33 cases (75.0%), with T waves inversion in V1~2 in 7 cases (15.9%), T waves inversion in V1~3 in 15 cases (34.1%), T waves inversion in V1~6 in 6 cases (13.6%), ST segment depression in 23 cases (52.3%), SⅠQⅢTⅢpattern in 11 cases (25.0%), and atrial arrhythmia in 7 cases (15.9%). It was two to four weeks after thrombolytic or anticoagulant therapies that ECG turned to being roughly nor-mal in 36 cases (81.8%). Conclusion ECG contributes to the diagnosis of acute pulmonary thromboembolism and therapeutic evaluation after thrombolytic or anticoagulant therapies.%目的：探讨急性肺血栓栓塞症的心电图特征。方法回顾性分析确诊的44例急性肺血栓栓塞症患者入院时及溶栓或抗凝治疗2~4周后的心电图变化。结果入院时出现心电图改变42例(95.5%)，其中窦性心动过速33例(75.0%)，Tv1~2倒置7例(15.9%)，Tv1~3倒置15例(34.1%)，Tv1~6倒置6例(13.6%)，ST段压低23例(52.3%)，SⅠQⅢTⅢ型11例(25.0%)，房性心律失常7例(15.9%)。溶栓或抗凝治疗2~4周后心电图恢复到大致正常36例（81.8%）。结论心电图有助于急性肺血栓栓塞症的诊断和溶栓或抗凝治疗后的疗效评价。
