Displacements of the apex beat due to intrinsic intrinsic conditions which may produce displacementof the heart and apex beat are — 1. Flnid in the sac of the Pericardinm.—Where the peri-cardial effusion is considerable, but not excessive, the base ofthe heart and the great vessels are pushed upwards andbackwards, and the apex is tilted upwards and outwards, sothat it may correspond in position to the left nipple, or insome cases may be situated still further to the left. Where the effusion is very copious, the apex beat may be completelyobscured ; while in those cases in which the amount of effusion is small(the heart itself being of normal size), or in which the heart is fixed byold pericardial adhesions, there is little or no alteration of the apex beat. 2.
