Supports posture-independence of circumferential shortening rate as contractility index; hypothesis-generating for validation in patients.
Do posture changes and isoproterenol administration affect the mean rate of circumferential shortening of the left ventricle in normal men?
The mean rate of circumferential shortening is a reliable index of left ventricular contractility that is independent of left ventricular end-diastolic volume and mean ventricular wall force of ejection.
Paley et al. (1971) studied this question.
