A comparison of attenuation compensated volume flow based Doppler echocardiography and impedance cardiography in healthy volunteers

Abstract

Attenuation compensated volume flow (ACVF) Doppler echocardiography (dual beam Doppler measures cardiac output independently of knowledge of aortic cross sectioned area and of angle of insonation. We compared a commercially available ACVF Doppler (Vital Science quantascop) with impendance cardiography (Boned, NCCON3) in 8, healthy volunteers
