Method and apparatus in order to correct an abnormal heart activity by the impacts of low energy

摘要

The apparatus comprises a detection electrode 12 mounted, for example, in the right ventricle, whose signal is applied to a sensor of arrhythmia 18 which, when it detected arrhythmia, such as tachycardia or fibrillation, transmits a signal has a programmable logic device 22 which causes the application to the core of a first electric shock of a low level by a device of the storage of energy 28. A sensor 20 of the speed of variation which receives the signal of the electrode of detection is then rendered active by the logic device and its output signal is continuously compared to a reference signal in a comparator 34 whose output signal is used for trigger then other shocks in synchronism with a feature recurrent of arrhythmia.
