Abstract

The present invention relates to an apparatus (40) for detecting and determining the magnitude of intracardiac shunts by the use of thermodilution. Two thermodilution curves are measured from different parts of the heart. The presence of an intracardiac shunt is detected by comparing (48) the shapes of the measured thermodilution curves with the shape of thermodilution curves obtained from a heart without a shunt. To determine the magnitude of an intracardiac shunt the areas below the measured thermodilution curves are calculated (52). This area-information is used for calculation (52) of the cardiac output and then the magnitude of the shunt.
