title: [Conventional roentgen functional diagnosis--videodensitometry. 3. Conventional roentgen videodensitometry exemplified by the heart].
abstract: It is possible to record movement parameters video densitometrically and synchronously by means of a video signal analysator at various points of the organ surface visible via fluoroscopic images (provided by videorecorder). Movement parameters of the heart surface were signed just in the same cardiac action by synchronous electrocardiography. There are some difficulties in this method according to evaluation with reference to laevocardiography in consequence of functional variety of the heart and the different exercise conditions. Small aneurysms of the cardiac apex were only seen when they were separated and located at the cardiac margin. Extended cardiac aneurysms were video densitometrically recorded as a paradoxical movement at the cardiac surface. A paradoxical movement was never seen with negative findings in laevocardiography.
