Programmable tachycardia pacer

摘要

A programmable implantable pacer is provided for performing the dual functions of demand pacing as well as standby tachycardia breakup. A command parameter control is used for programmably controlling parameters of the pacer operation as well as of the tachycardia recognition and response to same. Upon recognition of tachycardia, a series of stimulus pulses of predetermined rate and number are delivered, the tachycardia breakup pulses being generated and delivered through an output circuit utilized commonly with the demand pacer circuitry.
