Abstract:
1. An implantable device for determining a cardiac condition comprising: a detector adapted to substantially continuously detect a heart-related signal not limited by a cardiac cycle and for forming an input signal therefrom; an analysis unit connected to said detector and receiving said input signal therefrom, and producing a continuous analysis signal from said input signal having a real part substantially corresponding to said input signal and an imaginary part formed as a predetermined transformation of said input signal; a calculation unit connected to said analysis unit and receiving said analysis signal therefrom, said calculation unit calculating at least two heart-related parameters from said analysis signal dependent on said real part and said imaginary part; and a processing unit connected to said calculation unit and supplied with said heart-related parameters therefrom, said processing unit combining said heart-related parameters in a predetermined manner and identifying a cardiac condition therefrom.
