[Simultaneous observation of parameter of intraventricular pressure and energy metabolism in rat hearts using nuclear magnetic resonance].
A technique for simultaneous observation of parameters of intraventricular pressure and energy metabolic status in isovolumic rat hearts was described. The parameters of intraventricular pressure were collected and processed using a computerized monitoring system for heart function, and myocardial energy metabolism was investigated by collecting the 31P NMR spectra. The preparation was stable metabolically and functionally for 2 h under the NMR experimental conditions.
