Title
(EN) ANALYZING ECAP SIGNALS
(FR) ANALYSE DE SIGNAUX ECAP
Abstract
(EN) Systems, devices, and techniques are described for analyzing evoked compound action potentials (ECAP) signals to assess the effect of a delivered electrical stimulation signal. In one example, a system includes processing circuitry configured to receive ECAP information representative of an ECAP signal sensed by sensing circuitry, and determine, based on the ECAP information, that the ECAP signal includes at least one of an N2 peak, P3 peak, or N3 peak. The processing circuitry may then control delivery of electrical stimulation based on at least one of the N2 peak, P3 peak, or N3 peak.
(FR) La présente invention concerne des systèmes, des dispositifs et des techniques pour analyser des signaux de potentiels d’action de composés évoqués (ECAP) pour évaluer l’effet d’un signal de stimulation électrique délivré. Dans un exemple, un système comprend des circuits de traitement configurés pour recevoir des informations ECAP représentatives d'un signal ECAP détecté par un circuit de détection, et déterminer, sur la base des informations ECAP, que le signal ECAP comprend au moins l'un parmi un pic N2, un pic P3 ou un pic N3. Le circuit de traitement peut ensuite commander l'administration d'une stimulation électrique sur la base d'au moins l'un parmi le pic N2, le pic P3 ou le pic N3.
