老年急性肺栓塞心电图变化特点

摘要

目的 探讨老年急性肺栓塞患者心电图改变的特点及临床意义.方法 选择老年急性肺栓塞患者76例,分析治疗前后心电图的变化.结果 76例急性肺栓塞患者均出现异常心电图改变,其中窦性心动过速63例(82.9％),aVR导联R波振幅增高57例(75.0％),V1～V4导联T波倒置加深42例(55.3％),SⅠ QⅢTⅢ现象40例(52.6％),房性或室性期前收缩16例(21.0％)等,治疗后心电图改变较治疗前明显改善,差异有统计学意义(P＜0.05).结论 心电图在急性肺栓塞发病初期多有异常改变,但改变缺乏特异性,通过心电图的分析,仍有一些特征规律可循,结合临床症状,认真分析心电图的细微改变和辅助检查,对急性肺栓塞的诊断有重要意义.%Objective To study the features of ECG in elderly patients with acute pulmonary embolism and its clinical significance.Methods Changes on ECG for 76 elderly patients with acute pulmonary embolism were analyzed before and after treatment.Results The ECG was abnormal for the 76 patients with acute pulmonary embolism,including sinus tachycardia in 63 (82.9％),elevated R wave on the aVR lead in 57 (75.0％),deep and inverted T wave on the V1-V4 leads in 42 (55.3％),and SⅠ QⅢ TⅢ in 40 (52.6％),premature beats in 16 (21.0％).The ECG was significantly better after treatment than before treatment.Conclusion The ECG is usually abnormal for early acute pulmonary embolism patients without specific change on ECG.ECG can show its certain characteristic rules.Careful ECG analysis in combination with the clinical symptoms of patients and auxiliary examinations is of important significance for the diagnosis of acute pulmonary embolism.
