    摘要: A monitoring device for a patient for predicting a cardiovascular anomaly and a method for operating a monitoring device is provided. Furthermore, an implantable electrotherapy device, such as an implantable cardiac pacemaker, an implantable cardioverter, or an implantable defibrillator, having a monitoring device are also provided. In an embodiment, the monitoring device acquires a value change of a hemodynamic parameter, which occurs as a result of a detected value change of a state parameter, for example, as a result of an activation or deactivation of a cardiac resynchronization therapy. By suitable evaluation of the value change of the hemodynamic parameter, the monitoring device can output an evaluation result signal which is indicative of an imminence of a cardiovascular anomaly, such as a cardiac decompensation, long beforehand and with high specificity.

    摘要: 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).

    摘要: An implantable medical device has an impedance or admittance determination unit, an alternating current or voltage source, a measuring unit, and an analysis unit which is connected to the alternating current or AC voltage source and the measuring unit to calculate an impedance value or an admittance value at different times. The impedance or admittance determination unit may generate measuring current having two different frequencies (preferably below 100 kHz), and the analysis unit may calculate pairs of impedance or admittance values which are chronologically assigned to one another for different frequencies of the measuring current, and calculate a value for a blood impedance or blood admittance component which is independent of the impedance of the body tissue surrounding a particular blood vessel, The analysis unit may also determine trends in this value over time as an indicator for a change of blood hematocrit value.

    摘要: 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.
