Text Appearing Before Image:

a rule, louderand sharper than in health (hypertrophy of the right heart isalmost always associated with a considerable degree of dilata-tion) ; the second pulmonary sound is accentuated, and some-times reduplicated. The radial pulse is, in most cases, smalland weak (in consequence of the mitral lesion or lung diseasewith which the hypertrophy of the right ventricle is associ-ated), and it never presents the firm hard sustained characterwhich it has in many cases of hypertrophy of the left ventricle.The venous circulation is often congested. (Congestion of thesystemic venous circulation is a sign of failure of the rightheart rather than of increased strength, and is indicative ofdilatation rather than hypertrophy ; it must, however, be re-membered that some dilatation is almost always combinedwith the hypertrophy, and, as a matter of fact, some venousengorgement is not uncommon in cases in which signs ofhypertrophy of the right heart are well marked.) Hypertrophy of the Auricles. 6oi

Hypertrophy of the left auricle is,as we have previously seen, one means by which an obstruc-tion at the mitral orifice is compensated, and is, therefore,beneficial. It also occurs in some cases of mitral regurgita-tion. Hypertrophy of the left auricle is not attended by anypositive symptoms or physical signs except perhaps the pre-sence of an exaggerated auricular wave i
