摘　　要：目的:探讨心电图与超声心动图联合诊断肺栓塞的价值。方法:对已确诊急性肺栓塞20例患者的心电图和超声心动图检查结果进行进行统计分析。结果:心电图表现:窦性心动过速9例,占45%;ST-T改变8例,占40%;房性早搏2例,占10%;心房颤动1例,占5%。其中合并完全性右束支传导阻滞4例,肢导低电压4例,顺钟向转位3例,肺性P波2例。超声心动图检查:20例中4例发现直接征象,即肺动脉管腔内被血栓实性低回声充填;13例表现为肺源性心脏病与肺动脉高压的间接征象;3例结果正常。下肢静脉检查中8例发现深静脉血栓,5例表现为静脉血流淤滞。结论:常规心电图与超声心动图的联合应用能提高肺栓塞的准确率。Objective：To investigate the value of ECG combined with echocardiography in diagnosing pulmonary embolism.Methods：The ECG and echocardiography of 20 patients with acute pulmonary embolism confirmed clinically were analysised.Results： The ECG findings of pulmonary embolism were the followings： sinus tachycardia was in 9 cases（45%）,ST-T changes in 8（40%）,atrial premature in 2（10%） and atrial fibrillation was in 1（5%）.Amomg 20 cases mentioned above,combined with complete right bundle branch block,low voltage limb lead,clockwise translocation and pulmonary P wave were in 4,4,3,2 cases respectively.Meanwhile,echocardiography presented as direct and indirect signs.The former was in 4 cases and the echocardiography showed low echo-level thrombus in the pulmonary artery,the latter was in 13 and the sign of hypertension pulmonary was manifested.The remanent 3 cases were normal.Deep vein thrombosis of lower extremity and blood flow stasis were found in 8 cases and 5 cases respectively in ultrasonogram.Conclusion： It is of importance to diagose pulmonary embolism using ECG combine with echocardiography
