The heartsounds vary in intensity at the apex. Symptoms of Fibrillation.—Fibrillation may be suspected if in addi-tion to diastolic murmurs at the apex drawn to the end of diastoleof the auricle there is persistent irregularity of pulse, cyanosis, ordyspnea, anasarca, and all the signs of cardiac Fig. 189.—Electrocardiogram. Chronic endocarditis, presystolic and systolic mitral murmur. Auricular fibrillation, absence of /-waves, irregularity of rhythm and oscillatory waves during diastole. Right ventricular predominance. Boy, twelve yearsof age. Diagnosis.—The diagnosis rests on the recognition of a mitralstenotic lesion accompanied by a regurgitant murmur with a diastolicmurmur at the apex occupying the whole of diastole and apt to bemistaken for an aortic regtn-gitation.

Treatment.—It is in these cases of mitral disease with fibrillation thatdigitalis attains its greatest utility.
