Patent ID: 8812109

Claim:
A cardiac stimulator comprising: a data collection module configured to obtain at least one left atrial pressure (LAP) signal representing cardiac behavior over a cardiac cycle of a heart, from a left atrial pressure sensor; a stimulation pulse generator module configured to generate and emit stimulation pulses with a timing between successive pulses that implements at least one of an AV delay and VV delay; an LAP signal processing module in communication with said data collection module, said LAP signal processing module being configured to identify an A-wave of the heart using the LAP signal, and to determine a maximum positive rate of change of the A-wave; and a parameter setting adjusting module in communication with said LAP signal processing module, said parameter setting adjusting module being configured to adjust said at least one of said AV delay and said VV delay to produce a reduction of said maximum positive rate of change of the A-wave.
