    摘要： A method for selecting a target vein for left ventricular lead placement for cardiac resynchronization therapy includes determining electrical dispersion for the first coronary vein by calculating the difference between (i) activation time at a location of the vein that has the latest activation time of a plurality of locations in the vein and (ii) activation time at a location that has the earliest activation time of the plurality of locations. The method may further include (ii) determining whether the magnitude of the electrical dispersion for the vein meets or exceeds a predetermined threshold selecting the vein if the vein meets or exceeds the predetermined threshold; or (ii) selecting, among several veins, the vein that has the highest electrical dispersion.

    摘要： An implantable medical device uses an implantable sensor for acquiring a physiological signal that is received by a digital signal processor. The digital signal processor is a multi-channel signal processor including a first signal processing channel having a first sensitivity for sensing the physiological signal and a second signal processing channel having a second sensitivity different than the first sensitivity for sensing the physiological signal.

    摘要： An implantable medical device and associated method for automatically generating morphology templates during fast cardiac rhythms, confirming a provisional template as a confirmed template, and using the confirmed template to classify subsequent detected arrhythmias. A provisional SVT template may be created during a fast ventricular rate and activated as a confirmed SVT template upon verification that the fast rate was due to an SVT. The confirmed SVT template may be used to discriminate SVT from VT/VF.

    摘要： An implantable medical device system and method detect oversensing of cardiac signals. A cardiac signal including first events and second events is acquired. Cardiac events are sensed in response to the cardiac signal crossing a first threshold. A filtered cardiac signal is determined from the sensed cardiac signal, and a second threshold is determined from the filtered cardiac signal. A sensed cardiac event is classified either as a first event when the sensed cardiac event corresponds to a filtered cardiac signal peak crossing the second threshold or a second event when the sensed cardiac event corresponds to a filtered cardiac signal peak being less than the second threshold. Classification of sensed cardiac events as second events is used in determining oversensing.
