Rotational kymography. Technique for automated analysis of cine left ventriculograms.
A new device provides an automatic photographic record of left ventricular contraction and expansion. A radially slotted disk is interposed between the moving cine left ventriculogram and a disk of photographic film. By rotating either the slotted disk or the film, a kymographic record of regional wall motion is obtained. Unlike more complex computer programs, the speed as well as the magnitude of contraction can be determined.
