  • Publication number: 20190076652
    Abstract: Methods and devices are is provided for controlling a pacing therapy utilizing left ventricular multi-point pacing (MPP). The method and device provide electrodes configured to be located proximate to an atrial (A) site, a right ventricular (RV) site and multiple left ventricular (LV) sites of the heart. The method and device utilizes one or more processors. The processors determine atrial-ventricular conduction delays (AVCD) between the A site and multiple corresponding LV sites and determines pacing latencies at the LV sites. The processors adjusts the AVCDs, based on the pacing latency at the corresponding LV sites, to form atrial-ventricular latency adjusted (ARPL) conduction delays for the corresponding LV sites, calculates interventricular pacing (VV) delays for combinations of the LV sites based on the corresponding ARPL conduction delays and manages pacing therapy, that utilizes left ventricular MPP, based on the VV delays for the corresponding LV sites.

Electrodes are configured to be located proximate to an atrial (A) site, left ventricular (LV) site and right ventricular (RV) site of the heart. A conduction different ? is determined based on i) an atrial-ventricular conduction delay (ARRV) between the A site and the RV site, and ii) an atrial-ventricular conduction delay (ARLV) between the A site and the LV site. A correction term ? is based on intrinsic inter-ventricular conduction delay (IVCD) between the LV and RV. An LV atrial-ventricular pacing (AVLV) delay is set based on the conduction difference ?, a pacing latency PL and the correction term ? and manages the LUV pacing therapy based on the AVLV delay, wherein the LUV pacing therapy lacks pacing in the RV.

  • Patent number: 10016607
    Abstract: Techniques are provided for use with an implantable medical device for assessing stroke volume or related cardiac function parameters such as cardiac output based on impedance signals obtained using hybrid impedance configurations that exploit a multi-pole cardiac pacing/sensing lead implanted near the left ventricle. In one example, current is injected between a large and stable reference electrode and a ring electrode in the RV. The reference electrode may be, e.g., a coil electrode implanted within the superior vena cava (SVC). Impedance values are measured along a set of different sensing vectors between the reference electrode and each of the electrodes of the multi-pole LV lead. Stroke volume is then estimated and tracked within the patient using the impedance values. In this manner, a hybrid impedance detection configuration is exploited whereby one vector is used to inject current and other vectors are used to measure impedance.
