Patent ID: 8255063

Claim:
A cardiac stimulation configuration having: an electrode line comprising an electrical conductor; a proximal end, which is implemented to connect the electrode line to an implantable medical device; a distal end, which comprises at least one electrode coupled with said electrical conductor and implemented to deliver stimulation pulses or record intracardial electrical signals, and an acceleration sensor, wherein the acceleration sensor is implemented to record and differentiate acceleration values in at least two different directions; a radioopaque or echogenic section associated with said distal end; an implantable cardiac stimulator having a housing; a further acceleration sensor that is integrated in the housing of the implantable cardiac stimulator and wherein the further acceleration sensor is implemented to record and differentiate acceleration values in said at least two different directions and wherein said further acceleration sensor is configured to detect movement associated with physical activity of a patient; an analysis unit, which is at least indirectly connected to the acceleration sensor and the further acceleration sensor wherein said analysis unit is configured to analyze output signals from said acceleration sensor in relation to said output signals from said further acceleration sensor to compensate for said movement associated with said physical activity of said patient in which said electrode line is implanted to determine distance between said acceleration sensor and said further acceleration sensor that is independent of said physical activity of said patient; correlate said output signals from said acceleration sensor in said electrode line to hemodynamic findings obtained from a stress/echocardiography test on said patient that utilizes said radioopaque or echogenic section associated with said distal end of said electrode line to calibrate said output signals.
