Frequency domain cardiography and radionuclide ventriculography for evaluation of left ventricular function in coronary artery disease

摘要

Fifty-six patients with chest pain underwent selective coronaryangiography,radionuclide ventriculography (RNV) and frequency domaincardiography (FCG) to evaluate left ventricular function in coronary artery dis-ease (CAD).The sensitivity,specificity and accuracy of FCG were 87.5%,77.8%and 82.9%,respectively,which were slightly less than those of RNV (92.5%,88.9% and 90.8%,respectively).The changes of FCG scores were negatively corre-lated with changes of LVEF (r=-0.586,P0.01),and TS (r=-0.679,P0.01).These results indicate that FCG may be useful for the evaluation of leftventricular function in patients with CAD.
