    摘要: Safety pacing in multi-site cardiac rhythm management (CRM) devices is provided. According to various method embodiments, a first cardiac signal from a first cardiac region and a second cardiac signal from a second cardiac region are sensed. The first cardiac region is paced to maintain at least a minimum cardiac rate, and the second cardiac region is paced to maintain at least the minimum cardiac rate when a pace in the first cardiac region is inhibited. Other aspects and embodiments are provided herein.

    摘要: A cardiac rhythm management device that utilizes blanking or refractory periods to avoid misidentification of artifacts and evoked potentials, wherein the refractory periods are discontinuous and may be dependent upon sensed events, expiration of a predefined timing interval, or stimulation events in the same or other chambers of the heart. The discontinuous refractory periods enhance the ability of the device to sense intrinsic events. The present invention includes separate refractory and floating refractory periods incorporated within the sensing protocol for each selected cycle, thereby increasing the time period for normal sensing.

    摘要: A cardiac rhythm management (CRM) system provides for post-myocardial infarction (MI) therapy with closed-loop control using one or more ultrasound transducers sensing one or more ultrasound signals indicative of cardiac dimensions. Cardiac size parameters are produced using the one or more ultrasound signals to represent, for example, cardiac chamber diameter, cardiac chamber volume, cardiac wall thickness, infarct size, and degree of change in any of these parameters over time or between measurements. In various embodiments, such cardiac size parameters provide for titration, safety check, and acute optimization of the post-MI therapy.

    摘要: A system, method, or device classifies an arrhythmia according to the temporal order in which a depolarization wave associated with a particular heart contraction is received at a plurality of electrodes. One or more antiarrhythmia therapies is mapped to each arrhythmia classification. When a particularly classified arrhythmia is detected, the correspondingly mapped therapy list is selected and an appropriate antiarrhythmia therapy delivered. In one example, the particular therapy delivered in response to an arrhythmia depends at least in part on its historical success in treating arrhythmias of that classification.
