  • Pacing therapy adjustment based on ventriculo-atrial delay
    Patent number: 8755881
    Abstract: Techniques for adjusting pacing therapy based on ventriculo-atrial delay are described herein. These techniques may be used to control ventricular filling times during the delivery of pacing therapy. In some examples, a device or system delivers pre-excitation fusion pacing therapy to a ventricular chamber, determines a ventriculo-atrial delay interval for the ventricular chamber for at least one cardiac cycle, and adjusts the pacing therapy delivered by the implantable medical device to compensate for decreased ventricular filling time when the ventriculo-atrial delay interval is less than a threshold. In some examples, the device or system may adjust the pacing therapy by decreasing a pacing rate of the implantable medical device, increasing a pre-excitation interval for pacing of the ventricular chamber, and/or switching from a fusion pacing mode to a biventricular pacing mode.

  • Ventricular event filtering for an implantable medical device
    Patent number: 8060202
    Abstract: Pacing parameters are provided to address cross talk and intrinsic ventricular events occurring within a predefined blanking period following an atrial event. The parameters are used in conjunction with protocol for minimizing or reducing ventricular pacing, wherein ignoring intrinsic ventricular events during the blanking period might otherwise affect the performance of the protocol.
