Explaining Load-dependent Ventricular Performance and Energetics Based on a Model of E-C Coupling,ex of ventricular .. Evaluation of the energetics of the E(t) theory also led to the notion of a load-independent relationship between energy consumption (in the form of oxygen, mVO.) and mechanical energy liberation indexed by the pressure-volume area (PVA) (2).

In the absence of sufficient energy, cardiac performance deteriorates rapidly.

How to Select the Smoothing Parameter?,ave been reported to demonstrate regional abnormalities in contraction. Global indexes of left ventricular function (for example, ejection fraction) cannot detect such regional abnormalities of myocardial contractile function (3). To assess regional myocardial contractile function, many indexes have been proposed, as listed in Table 1.

Despite the importance of this arrhythmia, little is known about the cellular metabolism of the heart when it is subjected to ventricular fibrillation. In this study, phosphorus-31 magnetic resonance spectroscopy (P-NMR) was applied to isolated perfused ferret hearts to investigate the alterations in myocardial energetics induced by VF.
