to test whether verapamil protects myocardial high-energy phosphate content during hypoxia by reducing pre-hypoxic cardiac work or secondary to metabolic events that occur during hypoxia , we compared the relation between myocardial performance and high-energy phosphate content during normoxia , hypoxia and reoxygenation using 31p nmr spectroscopy in isolated , isovolumic buffer-perfused rat hearts .
