    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.

    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: An electromedical implant (100, 101, 102, 103) for monitoring a cardiac blood flow (B1) of a patient includes a detector (10, 10′, 10″) which obtains a first measurement signal (S1) associated with the cardiac blood flow (B1) and a second measurement signal (S2) associated with the epithoracic, peripheral blood flow (B2). A monitoring assembly (20) then generates a first parameter (P1) from the first measurement signal (S1) which is indicative of a time (tsys) at which blood is ejected from the heart, and a second parameter (2) from the second measurement signal (S2) which is indicative of a time (tgef) of a blood pulse in the thoracic tissue which is associated with the ejection of blood. An evaluation unit (30) then generates a pulse transit time (Δt=tgef−tsys) from the first parameter (P1) and the second parameter (P2). The detector (10, 10′, 10″) includes an impedance measuring unit (12) having an electrode assembly (11, 11′) for detection of at least the second measurement signal (S2) in the form of an impedance signal.

    摘要: The invention concerns implantable cardiac stimulation devices in general which have at least one stimulation pulse generator (A-STIM; RV-STIM; LV-STIM) to selectively generate a stimulation pulse for delivery to one of at least two different chambers of a heart, said chambers include right and left atria and right and left ventricles, at least one impedance measuring stage (I, U, IMP) being connected to electrodes or connectors for such electrodes to measure an intracardiac impedance when in use, a control unit (CTRL) connected to the stimulation pulse generator and to the impedance measuring unit and being adapted to process a minimum impedance value for a heart cycle to trigger stimulation pulses for two different chambers of the heart with an adjustable time delay (VVD; AVD) and to adjust said time delay depending upon the measured intracardiac impedance minimum value. According to the invention the control unit is adapted to adjust the time delay such that the minimum value of the intracardiac impedance during one heart cycle is minimized or such that the AVD delay is equal to the time interval between an atrial event and the point of time when the minimum impedance value occurs after said atrial contraction.
