title: [Possibilities of a corrected orthogonal vectorcardiogram (Frank) in the hemodynamically overloaded ventricular musculature].
abstract: The possibilities of the orthogonal corrected Frank system to establish the degree of the hemodynamic disturbance are analyzed in 220 cardiac patients. The sensitivity of the vcg-indices in patients with right-ventricle loading reaches up to 72 per cent and in patients with-left-ventricle-up to 100 per cent. The highest correlation coefficient in patients with right ventricle loading is 0.73 and in patients with left-tventricle-0.65 (p less than 0.01). the inferior diagnostic value of vcg-indices in patients with aquired heart defects is stressed. The value of the separate vcg-indices is discussed.
