A Total of 571 cases observed from November 1982 to February 1983 has been analysed. These cases were taken at random from 11 hospitals in Jilin, Tonghua and Guangzhou. Of these, 320 were patients with chronic pulmonary heart disease, 136 obstructive emphysema, and 115 miscellaneous heart diseases. A comparative study in regard to the abdominal signs was carried out. In patients with chronic pulmonary heart disease, 288 (90.0%) showed subxiphoid pulsation in contrast to 15 (13.0%) in the group of miscellaneous heart diseases (P0.01) .Subxiphoid pulsation is suggested as of the significance in the differential diagnosis as it is believed to be transferred from the antero=inferior wall of the right ventricle(always hypertrophic) via diaphragm to the abdominal wall. Tension of the abdominal wall was found in 241 (75.3%) in chronic pulmonary heart disease, in comparison to 18 (15.7%) only in miscellaneous heart diseases(P0.01). Overexertion of abdominal wall by cough, expectoation and abdominal respiration are thought to be the causes of tension of the abdomiual muscles, which may be also of some significance in the differential diagnosis.
