Anti - arrhythmia cardiac pacemaker operating at the request

摘要

P device of the cardiac stimulation anti - arrhythmia operating at the request and comprising several electrodes designed to be connected to a core in order to detect depolarization. A first circuit produces the signals of a stimulation to at least one region of the core if a depolarization corresponding to a natural heart beat not take place during a first predetermined lapse of time. A second circuit applies signals of a stimulation to several regions of the core when depolarizations are detected during a second predetermined lapse of time. / p
