急性肺栓塞的心电图早期诊断

Function of ECG for early diagnose of patients with acute pulmonary embolism

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 discuss the characteristics of electrocardiogram （ECG） for early diagnose of patients with acute pulmonary embolism and mechanism of change ECG. Methods Twelve routine lead ECG of 17 cases with acute pulmonary embolism were analyzed retrospectively and positive results rates about ECG and ultrasonic cardiogram （UCG） were compared. Results 14 cases appeared some kind of characteristics of ECG in 17cases. There weren＇t statistics differences about positive results rates between ECG and UCG （p〉0.05）. Conclusions There was the same function as ECG and UCG for early diagnose of patients with acute pulmonary embolism . So clinicians should not ignore the characteristics of ECG for the patients with acute pulmonary embolism. The patients would be treated and cured more early and gotten better prognosis, as the characteristics of ECG being early detection.
