    摘要: A method and device for determining an optimal lower rate and adjusting the programmed lower pacing rate to the optimal rate that includes monitoring a parameter in response to therapy delivered at a first rate during a first time period to generate first parameter data, and determining whether the therapy was delivered for a predetermined portion of the first time period. The parameter is monitored in response to the therapy delivered at a next rate during a next time period to generate next parameter data, and a determination is made as to whether the therapy was delivered for a predetermined portion of the next time period. A metric corresponding to the first parameter data is determined to generate a first parameter metric, and corresponding to the next parameter data to generate a next parameter metric used for determining an optimal therapy delivery rate.

    摘要: The invention is directed to techniques for applying overdrive pacing to one or both atria following termination of an AF episode, to prevent a recurrent AF episode. An implantable medical device such as a pacemaker applies overdrive pacing according to overdrive pacing parameters, and sets the parameters as a function of the response of the patient to overdrive pacing. The parameters may be adjusted upward or downward, so that overdrive pacing may be applied effectively but not over-applied.

    摘要: A pacing control is used in a multiple-chamber cardiac pacing system, which, upon detecting an atrial arrhythmia, automatically switches to a special therapy mode and administers a selected anti-tachycardia pacing (ATP) therapy in the atrium, and which switches to a standard pacing mode following delivery of the ATP therapy. The pacing control adjusts the timing of pacing pulses to be delivered to the atrium and/or the ventricle to minimize any potential ventricular pauses that may result from the switch from the therapy mode to the standard pacing mode.

    摘要: The efficacy of cardiac resynchronization therapy applied to a patient's heart by an implantable device are improved by obtaining acute hemodynamic feedback during implantation of a pacing device. A first and a second transducer are temporarily placed proximate to a portion of the patient's heart during device implant, and a distance between the transducers is monitored as the therapy is applied. A parameter (e.g. lead location, biventricular pacing, pacing rate, or the like) of the cardiac therapy is adjusted in response to the distance between the transducers until a desired result is obtained, after which the first and second transducers can be removed from the patient.
