1. Ultrasound diagnosisofpericardial effusion;Feigenbaum, H.; Waldhausen, J.A.; Hyde, L.P.;JAMA,1965
2. Cardiac motion in in "a few" patients to measure the volume of pericardial contents."7 He used a light-pen patients with pericardial effusion: a study using ultrasound cardiography;Feigenbaum, H.; Zaky, A.; Grabhorn, L.;Circulation,1966
3. Popp computational system to outline the borders of the pericardium and of the heart in the apical RL. Sensitivity and specificity of echocardiographic diagnosis of pericardial effusion;Horowitz, M.S.; Schulz, C.S.; Stinson, E.B.; Harrison, D.C.;Circulation
4. Echocardiographic quantifour chamber view. Volumes were computed electronically by an area-length single-plane tation of pericardial effusion;Parameswaran, R.; Goldberg, H.;Chest,1983
5. Reliability of echocardiography in quantitating pericaralgorithm. Schiller pointed out that an unavoidable shortcoming of this approach is that the pericardial border near the apical region cannot be visualised because it falls dial effusion: a prospective study;Prakash, R.; Moorthy, K.; Delvicario, L.; Aronow, W.S.;JCU,1977
