Summary The properties of ejection sounds are described as they were found in a limited number of proven cases of simple pulmonary stenosis, pulmonary hypertension, congenital aortic stenosis and coarctation of the aorta. Pulmonary ejection sounds are commonly found in pulmonary stenosis, even in severe cases. They tend to occur earlier in systole in cases of severe stenosis than in cases of mild or moderate stenosis. They vary in intensity with respiration. In pulmonary hypertension, ejection sounds are also frequently present. They occur later in systole than in pulmonary stenosis and show little variation in intensity with respiration. Aortic ejection sounds are commonly found in congenital aortic stenosis and in coarctation of the aorta. They occur later in systole in coarctation than in aortic stenosis, and in the former they are often less sharp and less click‐like to the ear and rather broad and “split‐up” phonocardiographically. Ejection sounds are an additional physical sign in the conditions described, and they may at times be helpful in diagnosis.
