Abstract:
The evaluation of cardiac function alone from pressure and volume data can lead to misinterpretations. By linking of pressure and volume data a variety of new parameters can be calculated. Computer techniques allow the evaluation not only of cardiac work, but also of acceleration work and the efficiency of heart power. As an example of double blind study with CHD patients the measurement of such parameters under invasive diagnostics is demonstrated, facilitating a detailed evaluation of cardiac function.
