目的探讨心电图改变在急性肺动脉栓塞患者早期诊断中的价值及心电图改变的机理。方法回顾分析17例急性肺动脉栓塞患者早期常规12导联心电图特点并比较心电图、超声心动图异常发现率。结果14例出现某种典型心电图改变。心电图与超声心动图异常发现率比较,无统计学意义(p>0.05)。结论心电图检查在早期发现急性肺动脉栓塞患者中与超声心动图有相同的价值。临床医生不应该忽视急性肺动脉栓塞患者心电图的改变,通过观察心电图变化早期诊断急性肺动脉栓塞,使患者得到早期的救治和更加良好的预后。
Objective To investigate the value of ECG changes and the mechanism of ECG changes in the early diagnosis of patients with acute pulmonary embolism. Methods A retrospective analysis of 17 patients with acute pulmonary embolism in the early 12-lead electrocardiogram characteristics and compare electrocardiogram, echocardiographic abnormalities found. Results 14 cases of some typical ECG changes. Electrocardiogram and echocardiographic abnormalities found no significant difference (p> 0.05). Conclusions Electrocardiography has the same value as echocardiography in the early detection of acute pulmonary embolism. Clinicians should not ignore the ECG changes in patients with acute pulmonary embolism, early diagnosis of acute pulmonary embolism by observing changes in ECG, so that patients receive early treatment and a better prognosis.
