<p>A method comprising sensing a blood pressure signal, deriving a hemodynamic measure from the sensed blood pressure signal, adjusting an extra systolic stimulation control parameter in response to the hemodynamic measure, and delivering extra systolic stimulation pulses according to the adjusted control parameter. The sensed blood pressure signal may be a ventricular or arterial blood pressure signal from which an estimated cardiac output, end diastolic pressure, mean pressure or any other hemodynamic measure is derived. Adjusting the extra systolic stimulation control parameter may include adjusting a pacing rate, a pacing interval, an extra systolic stimulation ratio, an extra systolic stimulation interval or enabling or terminating the extra systolic stimulation.</p> |
