Abstract

Methods and systems for programming a plurality of leads under at least two distinct modalities are provided. The leads may be grouped within satellites and multiple satellites may be configured within a single lead. Each lead includes a power and communications bus providing commands, and information and pulses to the satellites. The leads may be connected to at least two different command and pulse sources, optionally a cardiac pacemaker and/or a cardiac pulse analyzer system. A command may include or be preceded by a wake-up pulse that facilitates identification of a modality applicable to the associated command and data. A command may further optionally include a reference pulse or series of reference pulses, whereby the satellite references data pulses in relation to one or more aspects of the associated reference pulse. A data pulse may deliver two bits of information.
