Abstract

LITERATURE  Studies concerning the diagnostic significance of changes in the auricular or P wave of the electrocardiogram have not been numerous. Increase in height and prolongation of the wave, occurring most often in mitral stenosis, have been noted by Einthoven,1 Kraus and Nicolai2 and Samojloff;3 Goddard4 assumed a more or less definite quantitative relationship to exist between such augmentation of the P wave and auricular hypertrophy. He considered as increased all P waves when they were greater than T in the same curve, that isLITERATURE Checking this relationship, he found that there was some relative increase in height (of the P wave) in 54 per cent. of the cases of mitral disease studied. However, in five cases that came to necropsy, one with very slight hypertrophy of the auricle showed marked exaggeration of the P wave while another with decided hypertrophy showed only a slight relative alteration of the P.
