    • The invention concerns an implantable heart stimulating device (10) comprising, inter alia, a control circuit (14) adapted to enable at least the following: a) delivering electrical stimulating pulses to the two ventricles (RV, LV) of a heart with a variable time interval (ΔT) between the pulses; b) sensing signals receivable from electrodes (31, 32; 41, 42; 51 , 52; 61, 62) positionable at two different positions in the heart, c) deriving an impedance value (Z) based on said sensed signals, d) determining a minimum value (Z min ) and a maximum value (Z max ) of said impedance value (Z) during a heart cycle, e) determining a relationship between said minimum (Z min ) and maximum (Z max )values, f) varying said time interval (ΔT) and monitoring said relationship over a plurality of heart cycles, g) setting said time interval (ΔT) such that said relationship fulfi1s a predetermined requirement. The invention also concerns a system including such a heart stimulating device (10) as well as a manner of using such a system.
    • 本发明涉及一种植入式心脏刺激装置(10),其特别地包括控制电路(14),该控制电路适于至少能够实现以下功能:a)将电刺激脉冲输送到心脏的两个心室(RV,LV) 脉冲之间的可变时间间隔(DeltaT); b)感测可定位在心脏中两个不同位置的电极(31,32; 41,42; 51,52; 61,62)的信号,c)基于所述感测信号导出阻抗值(Z),d) 在心脏周期中确定所述阻抗值(Z)的最小值(Z> min <)和最大值(Z> max <),e)确定所述最小值(Z> min <)和最大值(Z > max <)值,​​f)改变所述时间间隔(DeltaT)并监视多个心脏周期的所述关系,g)设置所述时间间隔(DeltaT)使得所述关系满足预定要求。 本发明还涉及包括这种心脏刺激装置(10)的系统以及使用这种系统的方式。
