If the heart is large, as is generallythe case in cardiac symphysis, the organ, by its ownweight, depresses the diaphragm, especially on the left,and obstructs its movements. In order to make sure thatthe decrease of excursion is not due solely to this cause,a second observation in recumbency should be made, theposition in which the weight of the heart has no effect. Ifas marked a reduction of the movements is found, thenthe hypothesis that adhesions reduce the excursion of thediaphragm (Figs. 133 and 134) can be considered.
