[Measurement of left ventricle asynergy by various measuring procedures. II. Findings in patients with post-infarction states].
In 30 patients with postinfarction condition (11 infarctions of the posterior wall, 11 infarction of the anterior wall, 8 aneurysms of the anterior wall) the regional contraction of the left ventricle was analysed by 3 different metrical methods (semiaxis, surface and angular method) on the basis of the kineventriculogramme in the 1st oblique diameter. With all 3 methods a significant reduction of the mean contraction amplitude could be proved in the affected ventricular region. Using the semiaxis method, in all 30 patients an asynergy could be identified. By the surface method 2 patients with infarction of the posterior wall and 1 patient with infarction of the anterior wall, by the angular method 3 patients with infarction of the posterior wall and 1 patient with infarction of the anterior wall were not established. According to the disturbance of the entire function of the ventricle the number of the segment with disturbed contraction was largest in the group with aneurysm of the anterior wall and smallest in the group with infarction of the posterior wall. Even here the semiaxis method showed the greatest and the angular method the smallest sensitivity.
