目的探讨急性肺栓塞(PTE)的心电图(ECG)动态演变特点。方法收集急性PTE患者治疗过程中的ECG资料,并对相关文献进行复习。结果急性PTE的ECG改变常见的有窦性心动过速、S_ⅠT_ⅢQ_Ⅲ、胸前导联T波倒置、右束支传导阻滞等。经过有效的溶栓或抗凝等治疗ECG可出现一系列的动态演变,包括心率减慢、S_ⅠT_ⅢQ_Ⅲ改善或消失、右束支传导阻滞改善或消失、房性心律失常消失、胸前导联T波倒置变浅或直立等。结论急性PTE的ECG表现具有其特征性和动态演变的特点,其动态演变有助于评价PTE的疗效和预后。
Objective To investigate the dynamic evolution of electrocardiogram (ECG) in acute pulmonary embolism (PTE). Methods The ECG data during the treatment of acute PTE patients were collected and the related literatures were reviewed. Results ECG changes of acute PTE common sinus tachycardia, S_ⅠT_ⅢQ_ Ⅲ, thoracic T wave inversion, right bundle branch block and so on. After effective thrombolytic therapy or anticoagulant therapy ECG can be a series of dynamic evolution, including the heart rate slowed, S_ⅠT_ⅢQ_Ⅲ to improve or disappear, right bundle branch block to improve or disappear, atrial arrhythmia disappears, chest lead T Wave inversion lighter or upright. Conclusion The ECG manifestations of acute PTE are characterized by its characteristic and dynamic evolution. The dynamic evolution of PTE can be used to evaluate the efficacy and prognosis of PTE.
