This study aims at Optimizing measured parameters to reflect underlying pathology in dyssynchronous hearts. This is an experimental study in patients were bioimpedance measurements are performed during implantation.
Patients who are eligible for implantation af a Cardiac Resynchronization Therapy Device according to European Society of Cardiology guidelines are included. Measurements are performed on implanted leads and stored for post Processing. The study entry ends for each patient With completion of the implantation procedure.

RECRUITINGOptimization of Bioimpedance measurements
Acquisition of absolute and imaginary bioimpedance signals from electrodes of known location within the heart at different input current frequencies. Pacing is performed from Three different electrodes during acquisition of bioimpedance acquisition forming Three different groups. Wavelets of the signals are analyzed within each Group and compared within the Group and between the Groups. Optimization is achived when a discrimination factor that is calculated is improved.
