摘　　要：目的 :应用超声心动图探讨西藏地区先天性心脏病的特点。方法 :对 80例可疑先天性心脏病患者进行超声心动图检查 ,确诊后行心外科手术。结果 :西藏地区复杂心脏畸形相对较少。心脏听诊假阳性率较高 ,主要发生于听诊可疑房间隔缺损中。房缺杂音略不同于内地。房缺中以小缺损多见。较大的动脉导管未闭患者的临床症状与大室间隔缺损相比明显较轻 ,且前者术后左室内径回缩显著。结论 :超声心动图因其准确、快速、经济等优点 ,尤其适用于西藏地区 ,是开展西藏地区心外科手术的前提保障。高原地区先天性心脏病特征与高原缺氧 ,肺动脉压增高之间可能存在密切关系。Objective:To discuss the characteristics among congenital heart diseases in Tibet by echocardiography.Methods:Eighty patients suspected with congenital heart diseases were selected with transthoracic echocardiographic examination.Some underwent surgery after diagnosis.Results:The incidence of complex heart abnormalities was less than that in mainland.The false positive rate was high in heart auscultation,which often occurred in atrial septal defect(ASD).The murmur of ASD was a little different from that of the main land.The diameter of ASD was often small.The patient with large patent ductus arteriosus always had lighter clinical symptom and the left ventricular diameter was reduced more obviously after operation than that of patients with large ventricular septal defect.Conclusionss:Because of its accuracy,speediness and economy,echocardiography is the security and guarantee of cardiovascular surgery in Tibet.The characteristics of congenital heart diseases in Tibet may be related to low oxygen content and high pulmonary arterial pressure.
