## Abstract Intracellular sodium (Nal) concentrations rose immediately and progressively during ischemia in the isolated heart. The intracellular double quantum filtered sodium coherence (DQ) intensity also increased during ischemia. However, when normalized for Nai, the DQ intensity began to fall

## Abstract During NMR experiments on isolated, perfused rat heart, we observed a 57% change in probe sensitivity when the perfusion buffer surrounding the heart was replaced by either a lowβionicβstrength mannitol solution or air and the heart was made ischemic. Such changes in sensitivity, should
## Abstract Each of six perfused rat hearts was subjected to 30 min of hypoxia followed by 60 min of reoxygenation. Inversionβrecovery data on the intracellular Na NMR signal, differentiated by a shift reagent, 6 m__M__ Dy(PPP)~2~, were obtained every 5 min, and __T__~1~ values were calculated. The
