心电图与心向量图诊断心房及心室肥大的对比分析

Contrastive Analysis on the Electrocardiogram and Vectorcardiogram Diagnosing the Atrial or Ventricular Hypertrophy

目的:探讨心电图(ECG)与心向量图(VCG)联合应用诊断心房、心室肥大的临床价值。方法:应用心电工作站对观察组300例及对照组300例进行单独ECG及VCG、联合ECG和VCG诊断心房、心室肥大,分别计算3种方法的敏感性、特异性、准确性并进行对比。结果:ECG和VCG联用对左心房、右心房、左心室、右心室、双心房、双心室肥大诊断的敏感性及准确性最高,ECG单独应用及ECG和VCG联用对右心房及双心房肥大的诊断敏感性相同,VCG单独应用和ECG和VCG联用对右心室肥大的诊断敏感性相同;3种方法对心房、心室肥大诊断的特异性相近;ECG和VCG联用诊断心房、心室肥大时结合临床资料可提高准确性。结论:ECG和VCG联用诊断心房、心室肥大可弥补心电图的不足。

Objective To probe the clinical value of the ECG plus VCG diagnosing the atrial or ventricular hypertrophy. Methods By establishing an ECG work station, the atrial or ventricular hypertrophy patients of 300 cases in observation group and 300 cases in control group were respectively diagnosed by only ECG or VCG or ECG plus VCG. The sensibilities, specificities and accdracies of the said three methods were calculated and the contrastive analysis was made. Results For the hypertrophies in left or right atrium or ventricle or doule atriums or ventricles, the ECG plus VCG method had a high sensibility and accuracy. For the hypertrophies in right atrium and double atriums, the only ECG method had the same sensibility with the ECG plus VCG method. For the righ ventricle, the only VCG method had the same sensibility with the ECG plus VCG method. For the specificity, the three methods almost had the same value. ECG plus VCG method combining the clinical material could improve the acuracy in the diagnosis of atrial and ventricular hypertrophies. Conclusion Diagnosing the atrial or ventricular hypertrophy through ECG plus VCG will cover the shortage of ECG in such field.
