oa South African Medical Journal - Electrokymography : a study of heart border motion in health and disease



The electrokymogram is an apparatus for the study of heart-border movement. A hundred normal healthy medical students were examined and the left atrial tracings obtained and compared with those found in a study of 35 cases of mitral valve disease. The plateau descriptionbed by Luisada et al. is discussed and found to differ in no way from that found by the authors in the examination of the normal. There are no characteristic features in the left atrium electrokymogram in mitral valve disease. Curves essentially of the same character are readily found on examination of normal individuals.
