LEADLESS CARDIAC PACEMAKER SYSTEM FOR USAGE IN COMBINATION WITH AN IMPLANTABLE CARDIOVERTER-DEFIBRILLATOR

摘要

A cardiac pacing system comprising one or more leadless cardiac pacemakers configured for implantation in electrical contact with a cardiac chamber and configured to perform cardiac pacing functions in combination with a co-implanted implantable cardioverter-defibrillator (ICD). The leadless cardiac pacemaker comprises at least two leadless electrodes configured for delivering cardiac pacing pulses, sensing evoked and/or natural cardiac electrical signals, and bidirectionally communicating with the co-implanted ICD.

主权项

1. A method of operating a cardiac pacing system comprising:
performing cardiac pacing functions in at least one pacemaker in combination with a co-implanted cardioverter-defibrillator (ICD) comprising:
delivering cardiac pacing pulses;sensing evoked and/or natural cardiac electrical signals; bidirectionally communicating among the co-implanted ICD and/or at least one pacemaker of a plurality of pacemakers; and communicating a code that signifies occurrence of sensed cardiac electrical signals and/or delivered pacing pulses, identifying an event type and/or location.
