title: [Left ventricular ejection fraction estimated by 2-dimensional echocardiography].
abstract: Visual assessment of the reduction of left ventricular volumes during the cardiac cycle, which is the basis for calculation of the left ventricular ejection fraction followed up from several planes in real time is close to the objectively assessed changes estimated by various time consuming methods from two-dimensional echocardiography by the one- or two-plane method. The author's method makes it possible to assess the left ventricular ejection fraction and to divide it for clinical needs into four groups: normal above 60%, slightly reduced 45-60%, reduced 30-45% and markedly reduced 30% or less. The described echocardiographic examination method is invaluable when practiced by an experienced worker with restricted time for examination.
