Abstract: A device for detecting the state of a heart on the basis of intracardial impedance measurement. The device has an impedance measuring unit, which has electrical terminals, configured to be electrically connected or to be connected to electrodes for delivering and detecting a current or voltage, and is implemented to ascertain an impedance on the basis of the dimension of the delivered current or voltage and the voltage drop caused by the current or the current caused by the voltage, as well as an analysis unit, which is connected to the impedance measuring unit and is implemented to derive a cardiac function parameter from a time curve of the impedance ascertained using the impedance measuring unit. The analysis unit analyzes the impedance curve assigned to a diastole and derives a cardiac function parameter characterizing the behavior of a heart during the diastole (filling phase of the ventricle).

Abstract: A device is connected to electrode leads which performs intracardiac impedance measurements, conducts a transient pacing protocol, analyses the impedance measurements, and generates an LV lead position quality factor. The transient pacing protocol includes a repeated change (“transitions”) between ventricular intrinsic rhythm and biventricular paced rhythm and may also include a variation of the atrioventricular delay (AVD) and/or the interventricular delay (VVD). The quality factor expresses the degree to which hemodynamic properties have improved due to BiV stimulation for the current LV lead position compared to intrinsic ventricular rhythm.

Abstract: A system, method and computer-readable storage medium are configured for the detection of electrical signals originating from a human or animal heart. In particular, for monitoring devices, it is desired to obtain electrical signals from a human or animal heart with electrical contacts at the body of an implantable medical device, hence without the need to implant electrical leads to the hearts.

The method includes the steps of receiving electrical signals in at least two sensing channels, combining the electrical signals for forming a combined channel, extracting a template from the signals of the combined channel, comparing incoming electrical signals with the template, and depending from the result of the comparison, performing at least one of controlling one or more devices and signaling the result.

A control unit is connected to the sensing channels and is adapted to process sensed electrical signals originating from first and second locations of the heart.
