    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 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 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.

    摘要: Ventricular arrhythmias are monitored and classified based upon various criteria. One criterion is PR dissociation which is determined by comparing the PR interval in a current RR cycle to a median PR value. If the current PR interval varies too far from the median, then dissociation is indicated. Often, there are multiple atrial events in a given RR interval and the PR value has been based upon the last atrial event in the cycle. An algorithm determines whether to use the last atrial event in a cycle or whether an earlier atrial event occurred and would provide a more accurate PR value.

    摘要: A method and device for generating a template that includes identifying events of a plurality of sensed events having predetermined characteristics as first selected events and generating the template from the first selected events. Events of the plurality of events having the predetermined characteristics are identified as second selected events, and a determination is made as to whether the template is valid in response to the second selected events. The template is updated from the second selected events in response to the template not being valid.
