title: Changes in double quantum filtered sodium intensity during prolonged ischemia in the isolated perfused heart.
abstract: Intracellular sodium (Nai) 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 after 40 min of ischemia, and remained depressed during reperfusion.
