Abstract
An operating method for an implantable cardiologic device comprises the following steps for detection of a significant event or condition a patient is subject to: measurement of intracardiac impedance; detection of the morphologic signal course of the impedance, based on at least two morphologically representative parameters of the signal course; continuous storage of the parameter data from a defined measuring period; computation of a correlation coefficient for the stored parameter data; and comparison of the correlation coefficient with a reference correlation coefficient, with transgression of a defined deviation of the correlation coefficient from the reference correlation coefficient indicating the presence of a significant event.

An operating method for an implantable cardiologic device, for detection of a significant event or condition to which a patient is subject, comprising:
- measuring intracardiac impedance;
- detecting a morphologic signal course of the intracardiac impedance, based on at least one morphologically representative parameter of the signal course;
- continuously storing said parameter from a defined measuring period;
- computing a correlation coefficient for said stored parameter;
- and
- comparing the correlation coefficient with a reference correlation coefficient, with transgression of a defined deviation of the correlation coefficient from the reference correlation coefficient indicating a presence of at least one of said significant event and condition.
