摘要： Techniques are provided for use with an implantable medical device for detecting and assessing heart failure and for controlling cardiac resynchronization therapy (CRT) based on impedance signals obtained using hybrid impedance configurations. The hybrid configurations exploit right atrial (RA)-based impedance measurement vectors and/or left ventricular (LV)-based impedance measurement vectors. In one example, current is injected between the device case and a ring electrode in the right ventricle (RV) or RA. RA-based impedance values are measured along vectors between the device case and an RA electrode. LV-based impedance values are measured along vectors between the device case and one or more electrodes of the LV. Heart failure and other cardiac conditions are detected and tracked using the measured impedance values. CRT delay parameters are also optimized based impedance. In this manner, multiple hybrid impedance measurement configurations are exploited whereby different vectors are used to inject current and measure impedance.

摘要： Techniques are provided for estimating left atrial pressure (LAP) or other cardiac performance parameters based on measured conduction delays. In particular, LAP is estimated based interventricular conduction delays. Predetermined conversion factors stored within the device are used to convert the various the conduction delays into LAP values or other appropriate cardiac performance parameters. The conversion factors may be, for example, slope and baseline values derived during an initial calibration procedure performed by an external system, such as an external programmer. In some examples, the slope and baseline values may be periodically re-calibrated by the implantable device itself. Techniques are also described for adaptively adjusting pacing parameters based on estimated LAP or other cardiac performance parameters. Still further, techniques are described for estimating conduction delays based on impedance or admittance values and for tracking heart failure therefrom.

摘要： Techniques are provided for use by implantable medical devices for controlling ventricular pacing using a multi-pole left ventricular (LV) lead. In one example, a single “V sense” test is performed to determine intrinsic interventricular conduction time delays (Δn) between the RV electrode and each of the LV electrodes of the multi-pole lead. Likewise, a single “RV pace” test is performed to determine paced interventricular conduction time delays (IVCD_RLn) between the RV electrode and each of the LV electrodes. A set of “LV pace” tests is then performed to determine paced interventricular conduction time delays (IVCD_LRn) between individual LV electrodes and the RV electrode. Optimal or preferred interventricular pacing delays are determined using the intrinsic interventricular conduction delay (Δn) values and a set of interventricular correction terms (εn) determined from the results of the RV pace test and the set of LV pace tests. With these techniques, overall test time can be reduced.
