[Retrospective analysis of the effect of vinpocetine infusion in ophthalmologic disorders].

Retrospective analysis of the effect of vinpocetine infusion in ophthalmologic disorders. The authors retrospectively examined the effect of vinpocetine infusion on various ophthalmological disorders. Based on the data of 280 patients they concluded that vinpocetine infusion has beneficial effects in numerous ophthalmologic disorders of vision and visual field.

Body surface potential field representation fidelity: analysis of map estimation procedures.

The first part of this study analyzed the spatial-temporal error distribution of the Lux-type limited lead system. Quantitative new evidence is reported that the 32-lead anterior subset estimates the further 160 leads with an average amplitude error less than 38.5 microV.

A new possibility in the study of heart activation: the nondipolar body surface map.

The main goal of the present paper is to study the temporal and spatial course of cardiac electrical activation noninvasively, and to acquire more information than can be obtained from conventional methods, such as electrocardiography or vectorcardiography. The single moving resultant heart dipole is determined from a set of measured body surface potential maps before dipolar and nondipolar theoretical body surface potential maps are calculated. These three kinds of maps are studied together in different electro-cardiological situations (normal, left and right bundle branch block, and necrosis) during the entire cardiac cycle.
