This, as already noticed, is a common result of endocarditis, the valves
being most obnoxious to disease in such cases. The _symptoms_ are those
mentioned under endocarditis as characterizing disease of the different
valves, such as incapacity for exertion, difficult breathing,
palpitation, irregularity or intermission of pulse, venous pulse,
abnormal heart sounds, unsteadiness of the limbs when driven, and
dropsical swellings in the limbs and elsewhere. The reader is referred
to endocarditis for particulars, it being borne in mind that these
symptoms are not in this case associated with fever.
Horses affected in this way are useless. Cattle may sometimes be
partially fattened by preserving them from all sources of excitement, by
keeping the bowels regular and by combating any paroxysms with
sedatives, such as aconite, veratrum, hydrocyanic acid, or opium, and
with digitalis.
