计算机心电图与计算机心向量图的联合应用

本研究利用两个计算机自动诊断系统，一个对心电图，一个对心电向量图进行分析，完成了对国际标准心电图库的联合诊断，产观察了单独诊断之间，单独诊断与联合诊断之间的差异，以进一步探讨心电图与心电向量图在诊断上的互补效应，以及ＣＳＥ研究中关于联合诊断优于单独诊断的机制。国际标准心电图库由１２２０个病例构成，其中正常者３８２例，左室肥大１８３例，右室肥大５５例，双室肥大５３例，前壁心梗１７０例，下壁心梗２７３

The combined use of computer assisted ECG and VCG diagnosis

The study uses two computer programs,one for the interpretation of ECG,the other for the interpretation of VCG,and the combination of these two programs in the diagnosis of CSE data base,in order to take an observation of difference between two methods and a further investigation to the benefice offered by ECG and VCG mutually regarding their diagnostic information.Here is the main results:The CSE diagnostic data base was composed of 1220 cases in total,with 382 of normal (NSA),183 of left ventricular hypertrophy(LVH),55 of right ventricular hypertrophy(RVH),53 of biventricular hypertrophy (BVH),170 of anterior myocardial infarction (AMI),273 of inferior myocardial infarction (IMI),73 of mixed infarction (MIX) and 31 of ventricular hypertrophy combined with myocardial infarction (VH MI).On them,the combination of ECG and VCG has the highest diagnostic performance in LVH,RVH,MIX and VH MI.Its total accuracy rate was also the highest among 3 classifiers.The ECG was more accurate than VCG in NSA,AMI,and conversely,VCG was superior to ECG in LVH and MIX.It is concluded that the combined interpretation of ECG and VCG made by the 12-lead ECG program and the VCG program was beneficial in the classification of ventricular hypertrophy,mixed myocardial infarction and the situation where both infarction and ventricular hypertrophy are present.
