Cardiac Device, Method and Computer Program Product

Abstract

A cardiac device is provided including a measuring electrode, a signal-processing unit and a post-processing unit. The measuring electrode is adapted to be positioned within the blood pool of a human or an animal heart, in order to measure a depolarization-signal. The signal-processing unit is connected to the measuring electrode and is adapted to remove signal components with frequencies lower than a cut-off frequency from the measured depolarization-signal. The post-processing unit is connected to the signal-processing unit and is adapted to determine, based on the Brody effect, a measure for a ventricular volume of the heart based on the modified depolarization-signal. Furthermore, a method for the determination of a measure for a ventricular volume of a heart and a computer program product for performing the steps of this method are provided.
