The rhythm of the irregular and of the intermittent pulse is abnormal, i. e., arhythmic. When the pulse is irregular the intervals between the individual pulse beats are of unequal duration. This is due to lack of innervation of the heart, as well as to exhaustion of the organ. If the pulse of the horse exceeds 80 it is usually irregular. Irregularity is also ob- served in valvular diseases of the heart, and in myocarditis. The pulse is intermittent when a beat fails now and then. When regularly intermittent, a certain beat can nqt. be felt, as for instance, every fourth or fifth pulse wave; when irregularly intermittent there is a lapse which does not occur between any certain beats. The intermittent pulse is commonly physiological, and seen in perfectly healthy horses and dogs, where it disappears after exercise and, therefore, probably due to lacking innerva- tion. Pathologically it appears in chronic hydrocephalus (dummies), severe gastric troubles, and during convales-.
