Abstract
A multi-chamber pacing system has a pulse generator for successively delivering pacing pulses to chambers of a patient's heart, and IEGM signal detectors, having blanking intervals following the delivery of pacing pulses, including sensing circuits for sensing IEGM-signals from each of the heart chambers. Each of said sensed IEGM signals has a generally known morphology. A signal-reconstructing unit reconstructs the IEGM signal from one of the heart chambers in the blanking interval following delivery of a pacing pulse to another heart chamber.
Claims14
A multi-chamber pacing system comprising:
- a pulse generator for generating pacing pulses adapted for delivery to multiple chambers of a heart;
- a plurality of sensing elements adapted to respectively receive and sense IEGM signals from the multiple chambers;
- a control unit connected to said sensing elements for blanking sensing of said IEGM signals in respective blanking intervals following each delivery of a pacing pulse by said pulse generator;
- and
- a signal reconstructing unit connected to said sensing elements for reconstructing the IEGM signal from one of said multiple chambers in the blanking interval following delivery of one of said pacing pulses to a different chamber among said multiple chambers.
