Abstract
The present disclosure refers to a heart stimulator comprising a stimulation control unit, a stimulation unit, an impedance measurement unit and an impedance evaluation unit. The stimulation control unit is operatively connected to the stimulation unit to control timing of stimulation pulses by said stimulation unit. The impedance measurement unit is configured to determine an impedance signal reflecting intracardiac impedance. The impedance evaluation unit is operatively connected to the impedance measurement unit and to the stimulation control unit and is configured to evaluate the impedance signal so as to determine an isovolumic contraction time, an isovolumic relaxation time, an ejection time and a filling time from said impedance signal. The stimulation control unit is further configured to control timing of stimulation pulses depending on a performance index.
