Aim:To evaluate the diagnostic value of left ventricular diastolic function in patients with DCM by echocardiography.Methods:Indexes of left ventricular diastolic function in 20 DCM patients and 20 normal subjects were measured by echocardiography and radionuclide ventriculography(RNY).Results:RNV index (Peak filling rate ,PFR)in DCM was significantlydecreased compared with that of control group(P<0.05).Echocardiography indexes(νE,νA,νA/E) DCM group and control group.Conclusion:ECchocardiography indexes(ν...
