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… (More)
