Abstract
Results obtained on 7 subjects indicate that the min. volume of the heart is increased in the recumbent as compared with the erect posture. Ordinarily on prolonged quiet standing the output of the heart either remains unchanged or decreases slightly in subjects exhibiting no distress as a result of long standing. The heart output is decreased in subjects, who, on long quiet standing, display poor circulatory compensation in the erect position. A pulse pressure below 20 mm. Hg indicates a falling cardiac output.
