Is the teleost heart oxygen limited? - Insights using "hyperoxic" incubations of contracting cardiac tissue from rainbow trout.

In conclusion, the heart of female rainbow trout may be oxygen-limited in vitro and this study raises new questions about the choice of appropriate PO2 for experimentation, the relevance of elevated and varying PO2 to measurements of cardiac performance, and the possible existence of an oxygen sensor within rainbow trout cardiomyocytes.
