Abstract
Summary
Oxygen consumption measurements were made on trabeculae carneae from 7 contractile human hearts, obtained 1.8 to 8.4 hours after death. Mean QO2 was 21.0 ± 2.5, which compares favorably with mean in vivo oxygen utilization values reported for the normal human heart. There was no correlation between magnitude of the oxygen uptake and isometric tension developed by a sister preparation from the same heart, nor with the post-mortem interval.
