Abstract
Strips of left atrial muscle from the dog heart were subjected to varying degrees of stretch, and the work performed during contraction was calculated. Maximum work occurred at approximately 30% stretch. A theoretical analysis of these data indicates that maximum left atrial systolic work occurs at an intra-atrial pressure of 150 mm of water. © 1953, SAGE Publications. All rights reserved.
