据最近美国调查、室间隔缺损(以下简称“室缺”)的发病率较前增加50％。对该病的流行病学进行了调查,方法包括在不同的时间、地点及居民中调查该病的分布情况,以便发现引起该病的危险因素,并用医学知识对这些危险因素加以综合,找出因果关系进行比较。室缺的发病率升高,主要是因为近年依靠更完整的诊断技术发现病例较多。诊断标准的不同也造成各地方报告的发病率有些不同。有些已知导致室缺的危险因素:包括有先天性心脏病家族史,接受某些药物、感染因素及母亲患某些代谢性疾病等,这些危险因素只在少数病例中找到。该病发病率不
According to a recent U.S. survey, the incidence of ventricular septal defect (hereinafter referred to as “ventricular septal defect”) increased by 50% compared with the previous. The epidemiology of the disease was investigated by investigating the distribution of the disease at different times, places and residents in order to identify the risk factors responsible for the disease and to synthesize these risk factors with medical knowledge to identify Causality comparison. The increased incidence of ventricular outflows is mainly due to the discovery of more cases by more complete diagnostic techniques in recent years. Differences in diagnostic criteria have also resulted in somewhat different rates of reported localities. Some of the known risk factors for ventricular arrhythmia include a family history of congenital heart disease, certain medications, infectious agents, and certain metabolic disorders of the mother, which are only found in a few cases. The incidence of the disease is not
