[The value of Wagner and Selvester's electrocardiographic point indices for assessing global and regional function of the left ventricle in patients with ischemic heart disease].
The study includes 45 patients with ischemic heart disease. The reproducibility of Selvester's QRS-point index was examined by two researchers (r = 0.98). Between the ejection fraction of the left ventricle and the ECG-pont indices there exists a reverse relation, the correlation coefficients being equal (r = -5.58). Between the segmental disturbances of the left ventricular wall movements, examined by the systolic shortening in percentage of the radial axes, and both ECG indices there is also an equal correlation (r = 0.59). The relation between the angiographically evaluated segmental disturbances and the ejection fraction is also reverse, r = -0.88. The results of the study prove the relatively great possibility for mistakes of only the routine rest ECG is analyzed. The ECG evaluation of the left ventricular function cannot disclose the compensatory reserves of the healthy myocardium.
