title: [Video-densitometric demonstration of abnormal movement of the left ventricle compared with results of levocardiography (author's transl)].
abstract: Video-densitograms of the heart of 46 patients were obtained in three projections; these patients had clinically and angiocardiographically confirmed coronary disease of varying severity, or suffered from cardiomyopathy or were normal. The results were compared with levocardiography. The purpose of the investigation was to determine to what extent abnormalities of movement, seen on levocardiography, can also be demonstrated by video-densitometry. Our results show that video-densitometry, compared with levocardiography, has a sensitivity of 97%, a specificity of 44% and an accuracy of 86%. Video-densitometry provides definite proof of abnormal cardiac movement. The differentiation of hypokinesia from akinesia by the two methods is discussed.
