title: [Various methods of determining left ventricular stroke volume by using echocardiography].
abstract: The determinations of stroke volume (SV) were used with the aid of different formulae in patients with the ischaemic heart disease with areas of akinesia of the left ventricle, and those with the acquired mitral and aortal valve disease, congestive cardiopathy and in healthy individuals. Tetrapolar rheography was used as control. The calculation of SV with echocardiogram of the left ventricle in patients with areas of akinesia of the left ventricle and valvular regurgitation gives unduly high figures. The same data have been obtained in determining the SV with echocardiogram of the mitral valve with relative insufficiency. The figures of SV calculated with the echocardiogram of the aortal valve in patients with the disease of the aortal valve are lower as compared to the rheographic data.
