An implantable electric heart defibrillation system with attenuation of the pain resulting from the electric shock

摘要

An implantable electrical heart defibrillation system for both ventricle and atrium is proposed, wherein: the type of arrhythmia is diagnosed within a maximum time of 2 seconds from the onset of the arrhythmia; a therapeutic shock is delivered by electrodes implanted in the region to be defibrillated no more than 4-5 seconds after the recognition of the arrhythmia, if it is ventricular fibrillation, so that the patient does not loose consciousness; immediately after the onset of the arrhythmia and before the defibrillation shock is delivered, the conduction of neural pain signals coming from the region in which the electric shock acts is prevented, by means of nerve stimulation in the spinal column, or by the perfusion of a drug with immediate analgesic effect by means of an infusion pump and a catheter positioned in the region affected by the pain signals.
