[Accuracy of the rheographic method of evaluating stroke volume].
The results of stroke volume determination by means of integral tetrapolar body rheography (ITBR) and M-echocardiography were compared in 78 individuals, while Doppler cardiography was used as the reference method. Fairly high accuracy of stroke volume measurement by ITBR and its advantages over echocardiography, particularly the possibility of calculating the stroke volume irrespective of the heart size, are demonstrated. The accuracy of the ITBR determination declines in patients with severe heart failure.
