Patent ID: 7089058

Claim:
A multi-chamber pacing system comprising: a pulse generator adapted to interact with a heart for delivering pacing pulses respectively to multiple chambers of the heart; for each of the multiple chambers to which pacing pulses are delivered by said pulse generator, an evoked response detector including a sensor element adapted to interact with that chamber for sensing an IEGM signal, having a known signal morphology, therefrom and an integrator for integrating the IEGM signal within an evoked response detection time window to produce a time integral following delivery of a pacing pulse to that chamber, for detecting an evoked response of that chamber, said evoked response detection window containing a blanking interval resulting from delivery of a pacing pulse to another of said multiple chambers; and each evoked response detector having an integral reconstructing unit for reconstructing said time integral of said IEGM signal in said blanking interval.
