Dual chamber leadless pacemaker programmer and method

摘要

Systems and methods for providing communications between an external device and first and second leadless pacemakers (LPs) located in a heart are provided. A method includes receiving first and second event messages from the first and second LPs, the first and second event messages received at different points in time at the external device, determining the signal strengths of the first and second event messages, respectively, as received at the external device, adjusting first and second LP discrimination thresholds based on the received signal strengths of the first and second event messages, respectively, and utilizing the first and second LP discrimination thresholds to identify which of the first and second LP transmits subsequent event messages, in order for the external device to independently communicate with the first and second LPs.
