摘要: The present invention relates generally to methods and systems for optimizing stimulation of a heart of a patient. Hemodynamical index signals reflecting a mechanical functioning of a heart of a patient are recorded at different hemodynamical states. Corresponding hemodynamical reference signals at corresponding hemodynamical states are recorded. At least one hemodynamical index parameter is extracted from the recorded hemodynamical index signals. The at least one hemodynamical index parameter is a measure of the mechanical functioning of the heart and a hemodynamical index model is created, wherein the hemodynamical index model is based on the at least one hemodynamical index parameter and a comparison between output results from the hemodynamical index model and corresponding hemodynamical reference signals. From this hemodynamical index model, a hemodynamical index can be derived, which then can be used in determining patient customized cardiac pacing settings of the cardiac stimulator.

摘要: In an implantable sensor lead for sensing mechanical cardiac activity of a heart, as well as a sensing method and a cardiac stimulator embodying such a sensor lead, multiple cardiac activity sensing elements are distributed along a portion of a length of the lead body of the implantable lead. The sensing elements sense or detect mechanical cardiac activity and respectively emit electrical signals corresponding to the detected mechanical cardiac activity. The delivery of cardiac stimulation pulses can be controlled dependent on an analysis of the detected mechanical cardiac activity.
