Abstract：Objective To evaluate the diagnostic value of handheld echocardiography for heart diseases in Department of Emergency.Methods Totally 240 patients with undiagnosed heart diseases who were admitted to Department of Emergency of Beijing No.6 Hospital from June 2016 to December were enrolled.GE Vscan handheld ultrasonic diagnostic equipment was used for emergency bedside echocardiography by 2 trained doctors;evaluating indexes included cardiac atrioventricular diameters and wall thicknesses,pericardial effusion,regional wall motion abnormality,left ventricular systolic function and valvular lesions.GE Vivid E9 echocardiography was used for confirmed diagnosis of heart diseases.Consistencies of diagnostic results from 2 instruments and 2 doctors were analyzed.Results The handheld echocardiography showed 76 cases of atrioventricular enlargement,21 cases of ventricular wall thickening,36 cases of regional wall motion abnormality,27 cases of left ventricular systolic dysfunction,92 cases of valvular regurgitation and 4 cases of pericardial effusion.There was a good consistency between diagnostic results of GE Vscan handheld echocardiography and GE Vivid E9 echocardiography [Kappa coefficient(95％ confidence interval):atrioventricular enlargement 0.83 (0.75-0.90),ventricular wall thickening 0.88 (0.76-0.97),regional wall motion abnormality 0.82 (0.70-0.91),left ventricular systolic dysfunction 0.87 (0.76-0.96),valvular regurgitation 0.83 (0.75-0.89),pericardial effusion 1.00 (1.00-1.00)].The consistency between 2 doctors was good [Kappa coefficient (95％ confidence interval):atrioventricular enlargement 0.94 (0.89-0.98),ventricular wall thickening 0.92 (0.82-1.00),regional wall motion abnormality 0.87 (0.76-0.95),left ventricular systolic dysfunction 0.85 (0.73-0.95),valvular regurgitation 0.94 (0.90-0.98),pericardial effusion 1.00 (1.00-1.00)].Conclusion Handheld echocardiography can accurately show cardiac anatomical structure,function,hemodynamic status and provide effective reference for diagnosis of heart diseases.
