| ［摘要］ 肺栓塞心电图异常表现包括节律、QRS电轴以及形态等的改变，特别是胸前导联T波的变化，反映了血流动力学的异常，表现为右心室负荷过重导致心内膜下心肌缺血，这一异常表现与肺栓塞的严重程度显著相关。由于肺栓塞心电图改变的多样性、多变性等特点，其诊断肺栓塞的特异性是有限的。 |

| Abstract: |
| ［Abstract］ The electrocardiographic findings associated with pulmonary embolism have been widely studied in the medical literature. These abnormalities include changes in rhythm, QRS axis, and morphology, particularly in the QRS and T waves. Such findings may reflect hemodynamic changes, such as right heart strain, as well as myocardial ischemia associated with the disease. Although certain findings may correlate with the severity of pulmonary embolism, the overall utility of the electrocardiogram is limited due to the variable presence, frequency, and transient nature of most of the abnormalities associated with the disease. |
